Internal Design and Key Matrix Layout

This membrane keyboard uses a 36-key matrix with metal dome contacts. An encoder IC converts each key press into a unique BCD output code. The Siemens 6FM1496-1BB10 provides tactile feedback through the metal dome mechanism. Laser-etched labels resist fading from frequent operator use and chemical exposure. The keyboard includes a dedicated 10-digit numeric pad for fast data entry. Twenty-six function keys support custom programming for specific machine operations.

Installation and Compatibility Guide

First, cut a 232 mm x 75 mm opening in your control panel for mounting. Next, attach the keyboard using four M3 screws through the mounting holes. Then, connect the 20-pin ribbon cable to your display or positioning module. The host module automatically detects key presses without additional configuration. Each key sends a 4-bit BCD value plus a strobe signal to the host. This membrane keyboard works exclusively with Siemens 6FM1470 series display modules and 6FM1496 series positioning systems. Avoid using sharp objects on the membrane surface to prevent damage. Clean the keyboard with a soft, damp cloth only.
