M22-D-R
ActivoM22 Red Flush Push Button
Red flush momentary push button for Eaton M22 series. 22.5mm cutout, IP67 front. Complete unit with 1NC contact.
Aplicaciones comunes
Stop button used across manufacturing, particularly on European-built machinery. The M22 series is a direct cross-reference to Schneider Harmony XB4 — same 22mm cutout, same function, different manufacturer. Common on conveyor stop stations, machine tool auxiliary stops, and process control panels in chemical plants. The silver bezel provides good contrast against dark-colored panels, making the red button easy to spot in low-light factory environments.

Referencia rápida de instalación
Panel cutout: 22.5mm. 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.

Solución de problemas
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.

Lo que dicen los usuarios
“30mm is legacy at this point. Every major manufacturer has moved to 22mm as the standard. Eaton M22, Schneider XB4, Siemens SIRIUS — all 22mm. Unless you're maintaining a 1980s Allen-Bradley 800T panel, go 22mm and save panel space.”
