Guardmaster 440N Non Contact Switch (440N-Z21SS2BN9)

The non-contact safety switch 440N-Z21SS2BN9 is a reliable RFID-based guarding solution engineered to provide non-invasive, tamper-resistant safety protection for machine guards and doors. Its advanced sensing principle ensures that actuation occurs only when a coded actuator is properly aligned, adding a layer of security against bypass. Designed for industrial environments, the device comes with a pre-wired cable connection for straightforward integration, and a rugged housing that withstands challenging conditions.

With high safety performance, it’s suitable for demanding applications where rapid door opening is essential but safety must be maintained. The non-contact design eliminates wear and reduces maintenance, while the internal electronics deliver consistent actuation regardless of mechanical tolerances. This switch is ideal for modern automation systems needing highly reliable guard monitoring without contact-based mechanical wear points.
