Abstract
A bulkhead passthrough connector containing a printed circuit board (PCB) for transferring electrical signals across a bulkhead to an electronic valve actuator, an electronic valve actuator configured to operate and communicate with a valve using a PCB through a bulkhead, the electronic valve actuator, and a method of assembling a bulkhead passthrough connector incorporating a PCB. The embodiments may include a passthrough partition which separates one side of the bulkhead from another. A PCB retainer may also be secured to the passthrough partition. The PCB is attached to the PCB retainer and extends from one side to another side of the bulkhead through the passthrough partition. The PCB further includes electrical paths printed on the PCB and electrical connectors located on both sides of the bulkhead to enable communication with external devices.
