Membrane keypad for 6AV2123-2MB03-0AX0

Product Overview

The Membrane Keypad for 6AV2123-2MB03-0AX0 is a replacement membrane keyboard overlay / film designed specifically for the Siemens SIMATIC HMI KTP1200 Basic color PN (6AV2123-2MB03-0AX0), a 12-inch key/touch panel operator interface widely used in industrial automation and manufacturing environments.

The KTP1200 Basic PN is part of Siemens' SIMATIC HMI Basic Panel series, combining a 12-inch TFT widescreen display with key operation and analog-resistive touch functionality. The membrane keypad — also referred to as a keyboard membrane, membrane switch overlay, or MLM (Membrane Keyboard/Keypad) — is the front-face input interface covering the keypad area of the HMI panel. It provides the tactile push-button interface for operators navigating the HMI application. This replacement membrane is essential for maintaining HMI operability in environments where the original keypad has been worn, damaged, or has membrane seal failure due to heavy use, moisture exposure, or chemical contamination.
