Detailed Feature Overview

This membrane switch includes 14 tactile keys for user input. Each key requires 250 g of force with 0.8 mm travel. Consequently, operators receive clear tactile feedback for every press.

The sealed polyester overlay prevents dust and moisture ingress. An IP54 rating protects the front face from splashing water. The silver conductive circuit layer provides reliable electrical contact over time.

You will find a 14-pin ribbon cable extending from the rear. This cable connects directly to the S5 operator panel board. The 250 mm length gives you flexibility during panel assembly.

Installation and Compatibility

Siemens 6ES5393-0UA14 fits standard S5 operator panel cutouts. Clean the mounting surface thoroughly before attaching the membrane. Plug the ribbon cable into the matching panel connector carefully.
