Siemens 6FM1496-1BD00 | SIMATIC S5 Keyboard with Membrane

The 6FM1496-1BD00 serves as an operator input device for SIMATIC S5 systems. This membrane keyboard connects directly to compatible programming devices and operator panels. It allows users to enter data, navigate menus, and trigger control functions. Consequently, operators gain a reliable interface for machine interaction.

You can use this keyboard with various S5-compatible PG units. The 6FM1496-1BD00 features a sealed membrane surface that resists dust and liquids. This design makes it ideal for industrial environments with potential contamination risks. Therefore, the keyboard maintains reliable operation even under harsh conditions.

Key Layout and Physical Construction

The keyboard incorporates thirty-nine membrane keys in an optimized arrangement. The 6FM1496-1BD00 includes alphanumeric keys, function keys, and navigation controls. Each key provides tactile feedback through a metal snap-dome mechanism. The membrane surface protects internal components from dirt and spills.

A permanently attached cable connects the keyboard to the host device. The 6FM1496-1BD00 uses a standard PS/2 or proprietary Siemens connector. The unit contains no internal batteries or energy storage components. Below is a complete breakdown of its technical characteristics.

Interface Connection and Power Supply

The keyboard draws all operating power from the host device’s interface. The 6FM1496-1BD00 does not require any external power source or adapter. This passive design simplifies installation and reduces cabling requirements. A strain relief boot protects the cable entry point from mechanical stress.

You can clean the membrane surface using standard industrial cleaning agents. The 6FM1496-1BD00 withstands repeated cleaning without damage to the printed legends. Four rubber feet on the bottom prevent slipping on smooth surfaces. Therefore, the keyboard stays securely in place during operator use.

Operational Benefits for Control Rooms

This keyboard provides a cost-effective input solution for legacy S5 systems. The 6FM1496-1BD00 eliminates the need for standard PC keyboards in industrial settings. Its sealed design prevents failure from coffee spills or metal dust. Maintenance teams appreciate this durability for long-term reliability.
