Product description in English:

The magnetic safety sensor BNS 303-11Z-ST provides reliable monitoring of protective devices in industrial applications. With its low coding level according to EN ISO 14119, it is well-suited for applications with standardized requirements. The robust fiberglass-reinforced thermoplastic housing and IP67 protection ensure a long service life and high resistance to environmental factors.

The sensor operates on a simple magnetic principle with quasi-flush installation and is actuated by a magnet. With a service life of 20 years and a B10D value of 25 million switching cycles, it meets the highest safety standards. Switching distances of 5 mm (ON) and 15 mm (OFF) provide additional security.

Equipped with a 4-pin M12 connector, the sensor integrates easily into existing systems. The compact design, with an ISO thread M30 and a sensor length of 44 mm, simplifies installation. The safety sensor is ideally used in combination with recommended actuators from the BPS series and safety control units such as the SRB 301AN.
