Physical Dimensions and Construction
This membrane keypad measures 210 mm in width and 160 mm in height. Its thickness reaches only 1.2 mm for a low-profile design. The unit weighs 85 grams, adding negligible mass to the operator panel. A polyester top layer resists chemicals, oils, and mild solvents.
Key Layout and Tactile Feedback
Thirty-six membrane keys provide full input functionality for OP15 panels. Each key features a snap-dome mechanism for positive tactile feedback. You will feel and hear a click when pressing any button. The keypad includes numeric keys, function keys, and navigation arrows accordingly. Laser-printed legends resist fading from UV exposure and cleaning chemicals.
Connection Interface and Installation
A 36-pin flat ribbon cable connects the keypad to the OP15 main board. The cable extends 150 mm from the keypad edge for easy routing. You must remove the front bezel and old membrane before installation. Clean the sealing surface thoroughly to prevent dust ingress under the new keypad. Align the ribbon cable carefully to avoid pinching during reassembly.
Durability and Environmental Resistance
Each key withstands 1 million actuations under normal industrial use. The membrane construction prevents liquid ingress from splashes and spills. An adhesive backing seals the keypad to the panel bezel securely. Operating temperature ranges from 0°C to 50°C for factory environments. Test all keys for proper registration before fully tightening the bezel screws.
