Bernstein SLK-FVTU24UC-55-ARX Safety Switches

The Bernstein SLK-FVTU24UC-55-ARX is a magnetic safety interlock switch in Bernstein’s SLK series with a separate actuator, designed to guard large access doors and provide a monitored safety function for multi-contact circuitry. Operating at 24 V UC, this model offers 2 normally open and 2 normally closed contacts, enabling complex interlocks and guard-lock monitoring while the actuator states—withdrawn or inserted—are tracked to ensure proper locking. The device supports position monitoring of guard locking, with termination electromagnet and reporting on the contact position; electrical data lists utilization category AC-15 and a short-circuit protective device rating of 4 A gG, with E1/E3 and E2 behavior specified for both current and no-current conditions. A compact housing and a 400 mm actuator reach make the SLK-FVTU24UC-55-ARX suitable for large doors and applications requiring multiple contacts, delivering a robust mechanical-electrical interlock solution for safe access control in industrial machinery.
