Allen Bradley Guardmaster Prosafe RPSE Trapped Key Interlocks

Experience safe, simple, and reliable mechanical guard-locking with the Prosafe RPSE Trapped Key Interlocking units by Allen Bradley Guardmaster. The Prosafe 440T switches are an industrial-grade solution for securing machine guards and providing vital protection for personnel.

These safety switches ensure sequential access control, isolating the power supply to machinery when the safety guard is open. This helps to prevent machine operators from accessing potentially dangerous areas. These interlocks minimise risk of injury and downtime, allowing your operations to continue running smoothly and efficiently.

With Prosafe switches the new keys are fully compatible with old style barrels, however old keys do not fit the new barrels. This type of mechanical interlocking is usually used in environments where electrical interlocking systems may be unsuitable or expensive to install and maintain. The RPSE units also feature flush-mount housing. As the key is locked, the switch is ON and when the key is released, the switch is OFF.
