Part# MSI-MC310

The sensor system consists of the MC3x sensor, the MC3xA actuator, and the corresponding MSI-MC3x Safety Relay.

The sensor contains a special combination of reed contacts that are contactless activated by the coded magnetic field of the actuator. For guards that are accessible from behind, a reset button (RES) can be connected to the MSI-MC3x for manual starting. Evaluation of the RES signal is monitored edge-dependent.
