E-stops with self monitoring contact blocks

The M22 Line of operators have self-monitoring contact blocks for use with our E-Stop operators.

The M22 self-monitoring contact block offers additional safety in emergency stop applications. This device contains an additional normally open

contact that uses a unique plunger to monitor whether the contact block is still attached to the operator. In the event that the contact block

detaches from the emergency stop button, the self-monitoring contact block opens the circuit and stops the system – providing an extra

safety measure.
