Safety and access control solenoid interlock BD series

  Two-part access interlock   Comprising of a main body and catch   Complete with secondary lock portions   The catch is available in two options, suited to both well aligned and mis-aligned doors   Ideally suited for use on light duty panel doors, where the lock is subject to light to medium use   Manufactured in brass   Available with FS or Q type lock portions Application Castell BD multi key panel door interlocks are used as a part of a safety system, typically in machine guarding applications as in the below example. The power supply to the system is switched on and the access door to the hazardous area is locked closed. The removal of the isolation key in the KSS, changes the switch contacts provided for electrical supply to the electrical supply to the LV panel from closed to open. This key is then used to unlock the door by inserting key in the BD panel door interlock and releasing the trapped personnel key and then the catch. This will trap the isolation key in the BD interlock. The released key is taken by the personnel to the machine area. The power cannot be switched on until the personnel key is returned, the door is closed, the catch is trapped in the BD panel door interlock and the isolation key returned to the KSS.
