Magnetically coded safety
switches
Magnetic safety switches with N/O
or N/C contacts are evaluated safely
using a special input logic. Use of the
PSR-SACB4/4 sensor box or
PSR-SIM4 interface module is
recommended if you are using
several switches of this type. The
safety switches can thus be easily
interconnected as well as connected
to the PSR-SDC4 safety relay
without additional wiring.
