Schmersal BNS250-11Z Safety Interlock Switch For Doors

The Schmersal BNS 250-11Z magnetic safety sensor is designed for door interlocks on guarding doors in industrial machinery, providing safe, reliable signaling to safety circuits when the door is closed. This variant, Art. Nr. 101124743, ships with a 5.0 m cable, making it suitable for installations where the control cabinet is located at a distance from the door frame. It belongs to Schmersal's BNS 250 family of magnetic safety sensors used to monitor door position in safety interlock systems, with longer and shorter cable-length options such as 2.0 m (101120670), 2.5 m (101125869), 3.0 m (101126017), and up to 20.0 m (e.g., 101170859). Typical applications include safeguarding access doors on machines like CNC centers, conveyors, and robotic cells, ensuring the door must be closed for the safe operation of the equipment. Built by Schmersal, a leading supplier of safety switchgear, this sensor integrates with compatible door interlock assemblies to form a safety-rated door monitoring solution in harsh industrial environments.
