Schmersal BNS 303-02Z-ST-2211 safety sensor 101208000

Product Description in English:

The BNS 303-02Z-ST-2211 is a magnetic safety sensor with a fiberglass-reinforced plastic housing that is lightweight yet robust. Designed for flush mounting, it ensures reliable monitoring of safety devices and complies with EN IEC 60947-5-3 and BG-GS-ET-14 standards.

The sensor features two safety contacts (2 normally closed) and connects via a 4-pin M12 plug connector. Its reed contacts provide reliable switching performance with a maximum switching power of 10 W. With an IP67 protection rating, the sensor is protected against dust and water, operating efficiently in temperatures from -25 °C to +70 °C.

The assured switching distances are 8 mm when switching on and 18 mm when switching off. The BNS 303-02Z-ST-2211 is ideal for applications with protective devices moving frontally toward the active surface. Two mounting nuts (M30 x 1.5) are included for easy installation.

Recommended accessories include actuators such as BPS 300, BPS 303, or BPS 303 SS, as well as safety relay modules like SRB 219IT, SRB 308IT, or SRB-E-301ST.
