Schmersal BNS 303-11ZG Sensor

Schmersal BNS 303-11ZG is a coded, non-contact magnetic safety sensor in a robust M30 thermoplastic housing with a 1 m PVC-sheathed cable and an LED indicator that shows guard-door status, designed to pair with Schmersal SRB(-E), PROTECT-SELECT, or PSC1 safety-monitoring modules in EN 60947-5-3 safety circuits. It provides one NO and one NC contact, switching up to 24 V DC at a maximum 0.01 A (0.24 W), using a magnetic operating principle with no mechanical wear. The device is IP67 rated, suitable for ambient temperatures from -25 to +70 °C, and offers mechanical robustness with 10–55 Hz vibration resistance (1 mm) and 30 g/11 ms shock resistance. The 4-conductor cable (0.25 mm², PVC jacket) is 1 m long, facilitating flexible installation; actuator must be ordered separately, while mounting hardware (2x mounting nuts) is included. This LED-equipped version is suitable for food processing environments only in combination with the BPS 303 SS actuator. It resists transverse misalignment and soiling, reducing nuisance activations in dirty environments, and carries the 101138262 item number with EAN 4030661281148. With a sensor length of 44 mm, Schmersal’s BNS 303-11ZG delivers clear, immediate status feedback via its integral LED and offers a long-life, low-wear solution for reliable machine guarding.
