Schmersal BNS260-02ZG-ST-L Safety Interlock Switch

The Schmersal BNS 260-02ZG-ST-L is a compact magnetic safety switch from the BNS 260 family that provides two NC contacts for safety interlock circuits in gate or access‑door applications. It features a small plastic housing (26 x 36 x 13 mm) with an M8 x 1, 4‑pin connector, designed for a flush, hidden installation and IP67 protection, operating from -25 to +70 C. Electrical specifications include a maximum switching voltage of 24 VDC, maximum switching current of 0.01 A, and a switching power up to 0.24 W, with a rated short‑circuit current of 100 A. The device supports EN IEC 60947-5-3 and provides switching distances of S_on = 5 mm and S_ar = 15 mm, with Ui 75 VDC and Uimp 0.8 kV; tightening torque for the electrical connection is 0.3 Nm, and it withstands vibrations (10–55 Hz, 1 mm) and shocks (30 g, 11 ms). An integrated LED indicates the guard status, illuminating when the safety gate is closed, while the actuator must be ordered separately (BPS 260 is a recommended companion). This interlock switch is suitable for safety circuits where reliable door monitoring and fail-safe operation are required.
