Schmersal BNS260-11Z-ST-R Safety Door Interlock Switch

The Schmersal BNS 260-11Z-ST-R is a coded magnetic safety door interlock that monitors the position of movable guards in safety circuits in compliance with EN ISO 14119 and EN 60947-5-3. It provides 1 normally open and 1 normally closed contact, uses a four‑pin M8 connector, is IP67‑rated, and is designed for right‑handed doors (R) with an ST connector; this variant is specified without an LED status indicator. It is intended to be actuated only by BPS 260‑1 or BPS 260‑2 actuators and is used to terminate hazardous conditions immediately when the safety guard opens, integrating with Schmersal safety monitoring modules such as SRB(-E), PROTECT‑SELECT, or PSC1.
