Dimensions & Mounting

Mounting: Keypads may be mounted from the front or back of a panel. Front-mounted keypads need a small opening for the connection to the back of the keypad. Rear-mounted keypads require a cutout as shown in the drawings. For IP 67 sealing, a gasket is used in both cases.

Key Markings: Non-illuminated keys are engraved with the characters filled in black. Illuminated keys have cut-out characters backlighted with a yellow LED. The cut-out portion usually is left open for maximum illumination but can be filled with a transparent resin material for additional sealing. Custom markings and other LED colors may be obtained on special order.
