Schmersal BNS 33-12Z-2187 Coded Magnetic Safety Sensor

Schmersal BNS 33-12Z-2187 is a coded magnetic safety sensor designed for safety interlocks on machine guards. With a 10 m cable length, it pairs with Schmersal safety monitors such as SRB(-E), PROTECT-SELECT, or PSC1 to deliver coded, monitored switching and status signaling. It operates on a magnetic principle and complies with EN 60947-5-3 and EN ISO 14119:2013 for safe interlock systems, with a robust IP67-rated housing suitable for harsh industrial environments. As part of the BNS 33 family, the 12Z-2187 variant provides a specific coding for use in dedicated safety circuits and is intended to be integrated into Schmersal's safety ecosystem to achieve fail-safe protection of guarded machinery.
