Schmersal BNS260-11 01Z-ST-L Safety Interlock

Schmersal BNS260-11/01Z-ST-L is a coded-magnet safety interlock switch designed for securing movable machine guards and robotic work cells. The left-hinged door variant (ST-L) uses a magnetically actuated safety sensor to deliver 2NC + 1NO outputs and is intended for integration with Schmersal safety-monitoring modules such as SRB(-E), PROTECT-SELECT, or PSC1 to form a fail-safe guard interlock circuit. The device typically terminates via an M8 connector (six-pin) and is positioned for easy field connection in standard guard-door installations. It is housed in durable plastic and carries an IP67 rating, providing resistance to dust and water ingress in industrial environments, with an operating temperature range from -25°C to 70°C. In the 01Z variant, the interlock supports a sensing range of approximately 5–15 mm and a nominal supply voltage up to 30 V DC for the sensing and logic circuit. The BNS260 family is specified as a coded safety-sensor with a magnetic operating principle, designed to maintain guard integrity during operation and to release only when the safety circuit has been verified. This model is commonly used on movable guards for conveyors, robotic cells, and other machinery where a robust, wear-resistant interlock is required and where integration with standard safety-control architectures is essential for compliant risk reduction. Ensure the exact sub-model (BNS260-11/01Z-ST-L versus related variants) matches your catalog to confirm the precise contact configuration, voltage rating, and connector type.
