XB5RMA02
ActiveHarmony XB5R Wireless Push Button Green
Schneider Harmony XB5R — wireless push button requiring no wiring or batteries.
Common Applications
Battery-free wireless push button using energy harvesting — the mechanical energy from pressing the button powers the radio transmission. No wires, no batteries, zero maintenance. Uses Schneiders proprietary 868/915MHz protocol with ZB5RTA receiver. IP66 rated. Mount anywhere without running conduit. The future of industrial push buttons.

Installation Quick Reference
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Troubleshooting
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
