FANUC Teach Pendant Housing Replacement: How to Identify the Correct Case

A cracked, damaged, or worn FANUC Teach Pendant housing does not always mean the complete pendant needs to be replaced.

In many cases, the front cover, back cover, or another housing component can be replaced separately. However, selecting the correct replacement is not always straightforward.

FANUC Teach Pendants have different generations, configurations, and internal layouts. Two housings may look similar but have different mounting points, connector openings, keypad layouts, or internal component arrangements.

Ordering a housing based only on its appearance can result in an incompatible replacement.

This guide explains how to identify the correct FANUC Teach Pendant housing, distinguish front and back covers, check compatibility, and prepare the information needed to source the right replacement part.

1. What Is a FANUC Teach Pendant Housing?

The Teach Pendant housing is the protective enclosure around the pendant's display, keypad, internal electronics, and operating controls.

Depending on the model, the housing may consist of several separate components, including:

• Front cover or front case

• Back cover or rear housing

• Side grips and protective sections

• Handle or mounting features

• Keypad and display openings

• Cable connector mounting area

• Fastening points and internal support structures

The housing protects the internal components from physical impact, handling damage, and normal industrial operating conditions.

It also provides the mechanical structure that holds the display, keypad, circuit boards, switches, and other components in their correct positions.

The exact construction varies by Teach Pendant generation. Some models use separately replaceable front and back covers, while others have more integrated housing assemblies.

2. Common Signs That a FANUC Teach Pendant Housing Needs Replacement

A damaged housing can affect more than the appearance of a Teach Pendant.

The following conditions indicate that the enclosure should be inspected.

2.1 Cracked or Broken Front Cover

The front cover may become cracked after repeated impact, accidental drops, or long-term mechanical stress.

Common signs include:

• Cracks around the display opening.

• Broken sections near the keypad.

• Damaged screw or fastening points.

• Loose or separated housing sections.

• Deformation around the front panel.

A cracked front cover may no longer hold the display or keypad assembly securely.

2.2 Damaged Back Cover

The back cover protects internal electronics and provides support for the rear section of the pendant.

Possible damage includes:

• Cracks around the rear casing.

• Broken mounting posts.

• Damaged screw holes.

• Loose or missing cover sections.

• Deformation around the handle or grip area.

If the internal mounting points are damaged, simply tightening the housing screws may not provide a reliable repair.

2.3 Broken Handle or Side Grip

The handle and side grip areas are exposed to frequent handling.

Inspect these areas for:

• Cracks around the handle.

• Broken grip sections.

• Loose connections between housing components.

• Damaged mounting points.

• Signs of previous repairs.

A damaged handle should not be treated as a cosmetic issue if it affects how the pendant can be securely held.

2.4 Housing Damage Around the Keypad or Display

The areas around the display and keypad are particularly important because they support and position the input and display components.

A damaged housing may cause:

• Uneven keypad positioning.

• Poor alignment around the display.

• Loose or unstable membrane installation.

• Gaps around the screen or control panel.

If the keypad membrane or LCD is also damaged, inspect those components separately before ordering parts.

2.5 Liquid, Dust, or Contamination Damage

Cracks, broken seams, and missing housing sections can reduce the enclosure's ability to protect internal components.

If liquid, oil, or dust has entered the pendant, replacing the housing alone may not resolve the problem.

The internal keypad, connectors, circuit boards, and other affected components should also be inspected by qualified personnel.

3. FANUC Teach Pendant Front Cover vs. Back Cover

One of the first decisions when sourcing a replacement is determining which housing section is damaged.

Housing Component	Main Function	Typical Damage
Front Cover / Front Case	Supports and surrounds the display and keypad area	Cracks near screen, keypad, or front mounting points
Back Cover / Rear Housing	Protects the rear internal components	Broken screw posts, cracks, damaged rear enclosure
Side Grip / Handle Section	Provides structural support for handling	Broken grip, cracks, loose handle area
Complete Housing Assembly	Replaces multiple enclosure sections	Extensive housing damage or multiple broken sections

Not every FANUC Teach Pendant offers all these components as separately replaceable parts.

Before ordering, confirm whether the required replacement is sold as an individual cover, a housing section, or a complete assembly.

Also check whether the replacement includes any additional items such as buttons, membranes, seals, or mounting hardware. A plastic cover alone should not be assumed to include these components.

4. How to Identify the Correct FANUC Teach Pendant Housing

Correct identification is the most important part of the replacement process.

Use the following checks before placing an order.

Step 1: Find the Original Teach Pendant Part Number

Start with the identification label on the rear of the Teach Pendant.

Record the complete part number, including all letters, numbers, and suffixes.

FANUC Teach Pendant part numbers commonly begin with references such as A05B- or A290-, but the prefix alone is not enough to identify a compatible housing.

Do not remove or discard the original identification label during the repair process.

If the label is missing or unreadable, take clear photos of the front and back of the pendant.

Step 2: Identify the Teach Pendant Generation

Different FANUC Teach Pendant generations can have substantially different housing structures.

For example, older R-J3iB-era pendants and later R-30iB iPendant configurations may differ in:

• Front and rear cover geometry.

• Display dimensions and opening positions.

• Keypad layout.

• Internal mounting structures.

• Cable connector positioning.

• Handle and side grip design.

A housing that looks similar from the front may still have different internal mounting points.

Confirm the pendant generation before comparing replacement parts.

Step 3: Confirm the Exact Housing Part Number

If the original housing has a part number, use it as the primary reference.

If the number is not available, compare the replacement against the original housing using:

• Overall dimensions.

• Front and rear shape.

• Screw and mounting positions.

• Display opening.

• Keypad opening.

• Cable connector location.

• Handle and grip structure.

• Internal PCB mounting points.

The complete Teach Pendant model and clear photographs are particularly useful when the original housing reference cannot be identified.

Step 4: Check the Part Number Suffix

Do not ignore the suffix after the main part number.

For example, a reference such as A05B-2518-C202#EMH contains more information than the base number alone.

Different suffixes may indicate different configurations or specifications. A replacement should not be considered compatible simply because the base part number is similar.

Confirm the complete reference against the applicable parts documentation or a verified replacement listing.

Step 5: Check Internal Mounting Compatibility

This is an important step that is often overlooked.

A replacement housing may have the correct external shape but different internal mounting features.

Check whether the following can be correctly positioned:

• Main PCB mounting points.

• Display support and mounting locations.

• Keypad or membrane mounting area.

• Switch and control openings.

• Internal cable routing.

• Fastening points and supports.

A mismatch can prevent the original components from fitting correctly or may place unnecessary stress on internal connections.

Step 6: Confirm Safety-Related Component Fitment

FANUC Teach Pendants may include safety-related controls such as the Emergency Stop button and Deadman switch.

When replacing a housing section, confirm that the replacement supports the correct control arrangement and mounting structure.

Do not modify the housing to force a switch or safety component into an incompatible opening.

The Emergency Stop and Deadman functions must remain correctly installed and operational. Any repair affecting these components should be completed and verified by qualified personnel according to the applicable FANUC service documentation.

5. FANUC Teach Pendant Housing Part Number Examples

The following examples illustrate why exact part-number matching matters.

Part Number	Description / Reference
A05B-2518-C304#EMH	FANUC iPendant Plastic Cover
A05B-2255-C102#EMH	FANUC iPendant Plastic Cover
A05B-2518-C202#EMH	FANUC Teach Pendant Housing Reference

A290-7213-X703	FANUC iPendant Front Case
A290-7213-X706	FANUC Teach Pendant Back Cover

These are identification examples, not a universal interchangeability list.

The front cover, back cover, and complete pendant may have different part numbers. Some references may also represent a specific configuration or replacement assembly.

Always verify the complete part number and applicable pendant model before ordering.

For additional housing references, see the Robot Teach Pendant Housing & Replacement Shell Index.

6. How to Replace a FANUC Teach Pendant Housing

The replacement procedure depends on the Teach Pendant model and whether the front cover, back cover, or complete enclosure is being replaced.

The following is a general service overview. It is not a model-specific disassembly instruction.

Step 1: Identify the Damaged Housing Section

Determine whether the damage is limited to the front cover, rear housing, handle area, or multiple sections.

Inspect the surrounding components for additional damage.

Step 2: Confirm the Replacement Part

Compare the replacement housing with the original part.

Verify the part number, suffix, mounting positions, connector openings, and component layout before beginning the repair.

Step 3: Prepare the Pendant for Service

Stop the robot operation and place the equipment in the required safe maintenance condition.

Follow the applicable FANUC maintenance documentation for power isolation, cable disconnection, and ESD precautions.

Do not open or service a powered Teach Pendant.

Step 4: Remove the Damaged Housing

A qualified technician should follow the model-specific service procedure to remove the damaged cover.

During disassembly:

• Record the original component arrangement.

• Keep screws and fasteners organized.

• Avoid pulling internal cables.

• Protect the LCD and keypad assembly.

• Inspect internal mounting points for damage.

• Check for dust, liquid, or other contamination.

Step 5: Transfer the Original Components

If the replacement is supplied as a housing only, the existing internal components may need to be transferred.

Depending on the model, these may include:

• Display assembly.

• Keypad membrane or keysheet.

• Main circuit board.

• Switches and buttons.

• Internal connectors.

• Cable and strain-relief components.

Not every component is necessarily reusable. Inspect each part before transferring it.

Step 6: Install the Replacement Housing

Position the components according to the original configuration and the service documentation.

Check that:

• Internal boards are correctly supported.

• The display and keypad are aligned.

• No cables are trapped or pinched.

• All mounting points are correctly engaged.

• The housing closes without excessive force.

• The connector and external controls remain correctly positioned.

Do not force the two housing sections together if the mounting points do not align.

Step 7: Complete Functional and Safety Checks

After reassembly, follow the applicable service procedure to verify the pendant.

Check the display, keypad, cable connection, and other operating functions.

The Emergency Stop, Deadman switch, and any other safety-related controls must be verified before the robot is returned to operation.

Do not bypass or modify any safety-related circuit to complete a housing replacement.

7. Replace the Housing or the Complete Teach Pendant?

A damaged enclosure does not automatically require a complete Teach Pendant replacement.

The appropriate repair depends on the condition of the housing and the internal components.

Condition	Potential Repair Direction
Front cover cracked, internal components undamaged	Replace the front cover if separately available
Back cover or mounting posts broken	Replace the compatible rear housing
Handle or grip damaged	Check whether the relevant housing section is separately replaceable
Housing damaged and keypad membrane worn	Evaluate both housing and membrane replacement
Housing damaged and LCD or PCB also defective	Compare component-level repair with complete pendant replacement
Extensive damage or multiple internal components affected	Evaluate complete pendant replacement or professional repair

Component-level housing replacement may be practical when the damage is isolated and the internal components remain serviceable.

However, if several internal systems are damaged, replacing individual parts may not be the most appropriate solution.

The decision should be based on the actual condition of the pendant and the availability of compatible parts.

8. What Information Is Needed to Order a FANUC Teach Pendant Housing?

To avoid ordering an incompatible cover, prepare the following information before requesting a quotation.

Required Information	Purpose
Complete Teach Pendant part number	Identifies the original pendant configuration
Controller model	Helps confirm the applicable system
Original housing part number	Provides the strongest replacement reference
Front and back photos	Helps compare the external structure
Photos of the damaged area	Shows which housing section needs replacement
Required component	Clarifies front cover, back cover, or complete housing
Required quantity	Supports quotation and availability checking

If the original housing part number is unknown, clear photos are especially important.

Recommended photos include:

1. Full front view of the Teach Pendant.

2. Full rear view showing the identification label.

3. Close-up of the damaged housing section.

4. Close-up of any visible part number or molded reference.

5. Internal photos, only if the unit has already been safely opened by qualified personnel.

Providing these details helps reduce the risk of selecting a housing that looks similar but does not fit the original pendant.

9. Frequently Asked Questions

Can I replace only the front cover of a FANUC Teach Pendant?

On models with a separately replaceable front cover, it may be possible to replace only that section.

However, confirm the exact housing reference and internal mounting compatibility before ordering.

Are FANUC Teach Pendant front and back covers interchangeable?

No. Front and back covers have different structures and functions. Even within the same pendant generation, different configurations may use different housing references.

Can I use a housing from another FANUC Teach Pendant model?

Not based on appearance alone.

The mounting points, display opening, keypad layout, connector location, and internal support structure must match. Verify compatibility using the complete part number and applicable parts documentation.

Does a replacement housing include the keypad membrane and LCD?

Not necessarily.

A plastic cover may be supplied as a housing component only. Other items, including the keypad membrane, LCD, switches, and circuit boards, may need to be purchased separately.

Always confirm the supplied component list before ordering.

What if the original FANUC Teach Pendant label is missing?

Provide clear photos of the front, back, keypad, connector area, and damaged section.

If available, also provide the robot controller model and any part numbers found on the original internal components. These details can help identify a suitable housing reference.

Is it better to replace the housing or the complete Teach Pendant?

If the damage is limited to the enclosure and the internal electronics remain functional, a housing replacement may be a practical option.

If the pendant also has display, keypad, cable, or safety-related faults, the complete repair requirement should be evaluated before deciding.
