Industrial Push-Button Body Contact

This Schneider Electric Harmony XB4 body contact is a pre-assembled unit for industrial control panels. It combines a single normally open contact block with a metal fixing collar. The assembly accepts a separate head to create a complete push-button station. It is built for machinery and process panels that demand reliable operator interfaces.

22 mm Mounting with IP20 Protection

The component fits a standard 22 mm panel cut-out and uses push-in terminals for quick wiring. Its IP20 index guards against accidental contact with live parts during operation. The metal construction supports a wide operating range from -40 °C to 70 °C. Endurance is rated at 1 million mechanical cycles for reduced maintenance.

Supplied as Ready-to-Install Assembly

The contact block arrives factory-mounted on the fixing collar, so no separate collar is needed. Only a compatible Harmony XB4 head must be added to finish the button. Push-in terminals eliminate the need for screw-drivers during wire installation. This reduces panel build time and simplifies future contact replacement.

Questions about this item

What does the 22 mm size mean when the contact block is installed in a panel?

The 22 mm dimension matches the standard cut-out for Harmony XB4 operators, so the fixing collar mounts directly into that hole and the pre-assembled block sits flush behind the head.

How does the push-in terminal connection limit the wiring I can use?

Push-in terminals accept solid or ferruled flexible conductors up to the rated cross-section, giving a tool-free connection that locks the wire in place without a screw.

What does the 49 g weight tell me about mounting this block on a metal collar?

At 49 g the assembly is light enough that the metal fixing collar carries the load without extra support, even in high-vibration panels.
