Extracted key adaptor ensures machine safety

Safety interlocking company Fortress Interlocks has added the new E1, Extracted Key Adaptor, to its amGard range of modular safety gate switch interlocks. The E1 has been designed to ensure that the door to hazardous machinery cannot be opened without removing the safety key, and the machinery cannot then be restarted until the key is returned. Fortress has achieved this by designing a mechanism that traps the actuator in the head until the key is removed which then allows the 'gate' to swing over the keyhole.

While the actuator remains out of the head, the gate remains over the keyhole preventing the key being returned to the lock.

E1 ensures a specific sequence of operation and can be stacked or combined with other adaptors; up to five key adaptors can be used in one configuration. E1 works with access key and safety key adaptors, amGard LOK or STOP bodies and is suitable for either hinged or sliding door applications.
