New Safety Switch from Rockwell Automation Provides Interlocking on All Types of Guard Doors

December 15, 2020

The new Allen-Bradley Guardmaster 440G-EZ electromagnetic interlocking 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 uses a power-to-lock (PTL) magnetic locking function, which increases door stability, and reduces misalignment and nuisance tripping. With its high holding force and misalignment tolerance, the 440G-EZ switch is intended for use on all types of guard doors.

The 440G-EZ switch has a low-profile housing design. It has multiple mounting and connection options, including 5-pin or 8-pin M12 micro quick-disconnect pigtails for optimal installation flexibility.

To simplify installation, troubleshooting and maintenance, the switch offers onboard LED diagnostics, indicating switch status when the state of the output signal-switching devices are locked or unlocked.

The 440G-EZ safety switches are TÜV-certified up to Cat 4, SIL 3, PLe – the highest level of safety for guard position.
