Coded Magnetic Safety Switch and Control Unit

This high-integrity system consists of an electromagnetically coded magnetic safety switch, actuator, and control unit. The switch and actuator can be used as a stand-alone system for low-power, low-risk machines or with the control unit for applications requiring a higher level of integrity. The control unit should be used when monitoring and checking of the circuit is required. The 115/230-V AC unit monitors and checks up to six coded magnetic safety switches (wired in series); the 24-V AC/DC unit monitors up to fifteen coded magnetic safety switches (wired in series). If a failure is detected in any switch or in the control unit at a machine off/on cycle, a stop signal will be sent to the guarded machine. The control unit also provides monitoring of the machine's control contactor.

Safety contacts are normally open (NO) when the actuator is not actuating the switch.
