Trapped Key Interlocks with Single Key (Die-Cast)

Trapped Key Interlocks for access control ensure that a guard door remains securely closed during normal operation and can only be opened when the correct key code is presented. They are ideal for applications that require part body access, such as lids, hatches and small doors.

Once the key is inserted, the interlock will open, allowing access to the hazardous area. During this time, the key will remain trapped until the guard door is closed and the actuator is present.
