FAQ

The primary difference is the contact type. The M22-K01 is a Normally Closed (NC) contact, meaning the circuit is complete when the actuator is not pressed. The M22-K10 is a Normally Open (NO) contact, where the circuit is open until the actuator is pressed. The plunger color is also different for easy identification: red for NC (K01) and green for NO (K10).

Yes, the Eaton M22 modular system is designed for flexibility. You can stack up to three contact blocks on the mounting adapter for a standard M22 operator, allowing for various contact combinations to suit your application's logic.

For reliable and secure connections, Eaton recommends a tightening torque of 0.8 to 1.0 Nm for the screw terminals on the M22 series contact blocks. Using a calibrated torque screwdriver is advised for critical applications.
