Schmersal BNS260-02Z-ST-R Safety Interlock Switch

Schmersal BNS 260-02Z-ST-R is a coded, magnetic safety sensor designed for safeguarding safety doors on industrial machines. It belongs to the BNS 260 family and is intended for use with Schmersal SRB(-E) safety monitoring modules, PROTECT-SELECT, PSC1, or equivalent safety-oriented controllers to meet EN 60947-5-3 requirements. The device provides two normally closed (NC) contacts, enabling dual-channel interlock signaling for reliable door safeguarding, while its IP67-rated housing protects against dust and immersion in wet environments. It uses a magnetic operating principle and features a standard M8 electrical connection for robust wiring in confined spaces. This configuration makes it suitable for machine guarding on conveyors, presses, packaging lines, and other automated equipment where access needs to be controlled. By delivering coded magnetic sensing with dual NC outputs, the BNS 260-02Z-ST-R supports safer lock-and-release interlocks and coherent integration with Schmersal safety systems, ensuring consistent safety performance when paired with compatible monitoring modules.
