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.
Note: Key must be ordered separately
Standards: EN 292 and EN 1088, IEC 947-5-1, UL and CSA

How does a trapped key interlock work?
A trapped key interlock is a simple sequential mechanical safety system for machine guards whereby a removable key is trapped in a control device while the power supply is running. Only when the power supply is turned off can the key can be rotated in the lock and withdrawn. While it is removed the power supply is isolated, ensuring that the machine cannot be restarted while the guard door is open. The key can then be used to release the machine guard, allowing access to the machinery. After the guard is closed it can be removed and inserted back into the original control unit, thus allowing the power supply to be activated again. These interlocks can withstand harsher environments than electrical interlocks and are often used in industrial settings where serious risk of injury can occur to machine operators.
