Allen-Bradley® Guardmaster® safety switches help protect personnel, processes and equipment by providing physical interlocking of guard doors, allowing access to potentially hazardous areas only when the area is safe. The new 440G-EZ electromagnetic interlocking safety switch is designed to protect a working process from unplanned downtime to improve productivity and increase efficiency while providing personnel safety.

The new Allen-Bradley® Guardmaster®  electromagnetic interlocking safety switch can help protect people, processes and equipment. By providing the physical interlocking of guard doors, the safety switch allows access to a potentially hazardous area only when the area is safe. This can help keep people safe and protect a process from unplanned downtime to improve productivity and efficiency.

The 440G-EZ electromagnetic safety switch is a cost-effective interlock solution that combines a Power to Lock (PTL) magnetic locking function featuring a 500N holding force and with ±5 mm misalignment tolerance. Intended for use on all types of guard doors, 440G-EZ electromagnetic safety switches are TÜV-certified up to Cat 4, SIL3, PLe — the highest level of safety for guard position — and can be connected in series with other Cat 4, SIL 3 or PLe rated safety devices.

This safety switch also features a low-profile housing design with multiple mounting (surface or flush mount) and connection options including 5-pin or 8-pin M12 micro quick disconnect pigtails for optimal installation flexibility. The magnetic locking feature further aids in door stability and reduces misalignment and nuisance tripping. To simplify installation, troubleshooting and maintenance, the switch offers on-board LED diagnostics indicating switch status as well as when the state of the output signal-switching devices (OSSD’s) are locked or unlocked.

Built to global standards for high reliability, stability and quality, Allen-Bradley® Guardmaster® safety switches are ideally suited for applications where safety is a priority. Our innovative products help protect your people, machinery and environment while maximizing uptime
