The membrane keypad (also known as the keysheet or protective overlay) is the most frequently touched part of any robot system. Over time, exposure to industrial solvents, welding sparks, and repetitive use leads to cracked surfaces, unresponsive buttons, or obscured labels. Replacing a worn membrane not only restores the tactile feel of the Teach Pendant but also prevents oil and dust from penetrating the internal electronics.
This Teach Pendant Membrane Index is a comprehensive cross-reference guide for Fanuc, Yaskawa Motoman, ABB, and KUKA pendants. Whether you need a high-durability YKS-701E for DX200or a GNE2 protective film for Fanuc, we provide precision-cut, chemical-resistant overlays to restore your HMI to factory standards without the cost of a full unit replacement.

1. Visual Identification: The Cost of Neglect
Replacing a membrane before it cracks is the difference between a $50 repair and a $2,000 replacement.

When Should a Membrane Be Replaced?
Typical field indicators include:
- Buttons require excessive force or stop responding
- Printed legends become unreadable
- Surface cracking allows oil or dust ingress
- Sticky or swollen keypad due to coolant exposure
Early replacement helps prevent deeper electrical damage inside the pendant.
Installation Considerations
Professional Application Steps:
- Complete Removal: Peel off the old membrane. Use a plastic scraper to avoid scratching the pendant housing.
- Solvent Clean: Use Isopropyl Alcohol (90%+) to remove every trace of old adhesive.
- Dry Fit: Align the new membrane without removing the backing to ensure perfect placement.
- Pressure Application: Peel from one corner and press firmly, moving outward to eliminate air bubbles.
Frequently Asked Questions
Q: Is it difficult to replace the teach pendant membrane myself?
A: Most membranes use a high-strength adhesive backing. The key is to completely remove the old adhesive residue using isopropyl alcohol before applying the new keypad overlay to ensure a bubble-free, permanent seal.
Q: My buttons are still unresponsive after replacing the membrane. Why?
A: The membrane is the cosmetic and tactile layer. If buttons don't work after replacement, the underlying PCB (Circuit Board) or the internal conductive domes may be damaged. Check our Teach Pendant Repair Index for more details.
Q: How do I know if I need a "Protective Film" or a "Membrane Keypad"?
A: A Protective Film is a thin, clear layer to prevent scratches. A Membrane Keypad (like the Yaskawa YKS series) includes the printed button graphics and is the actual surface you press.
Q: Are these membranes resistant to hydraulic oil and cooling fluids?
A: Yes, our replacement membranes are manufactured from industrial-grade polyester or polycarbonate, specifically designed to withstand the harsh chemicals found in CNC and robotic welding environments.
