Bernstein AG SLK-FVTU24-230MC-22-ERRX Safety Guard Switch

The Bernstein AG SLK-FVTU24-230MC-22-ERRX Safety Guard Switch is a guard-locking interlock with a separate actuator designed to secure movable safety guards on industrial machinery and monitor guard closure. It is built for two-voltage versatility within Bernstein’s SLK family, offering operation at 24 V AC/DC or 110/230 V AC, and is configured to report guard status through integrated contacts. The unit features a thermoplastic enclosure (GV UL94-V0) and a robust IP67 protection rating for harsh industrial environments, with an actuating device that can be withdrawn or inserted to control the locking state.

• Contact arrangement: 2 NC safety contacts plus 2 NO auxiliary contacts for signaling.
• Electrical and voltage options: two operating-voltage variants—24 V AC/DC and 110/230 V AC (up to 250 V rated in some installations); compatible with 50/60 Hz systems.
• Environmental and mechanical: enclosure and actuator made from thermoplastic GV (UL94-V0); ambient temperature range typically from −25°C to +70°C; IP67 protection.
• Guard monitoring: designed for position monitoring of guard locking (actuator inserted or withdrawn) to ensure safe machine access controls.
