Our access interlocks are used to reduce risk when workers enter hazardous areas. Their purpose is to eliminate the possibility of energy restoration occurring while someone is near a machine. They achieve this by trapping a key that controls the electrical supply.
These products are typically made up of two parts; a main body and an actuator or latch. The main body will attach to the machine, and the actuator or latch will attach to a door or gate. When these two parts of the lock are separated (i.e. when someone is in the hazardous area) the key is trapped. It is only released when the actuator or latch re-engages with the main body, at which point the machine can be restarted but the person is out of the hazardous area.
