Johnson Electric provides global leaders in building automation with countless solutions for door locking applications. Our AC and DC solenoids are the most commonly deployed actuation technology for door locking functions. Found in university buildings, dormitories, factories, hospitals, schools or public facilities, the ability to electrically control access to secure areas is increasing in prevalence as concerns about individual safety increases. Often operated via swipe card access systems, a DC solenoid is operated with AC power and an audible hum results. This provides feedback to the entrant that the locking mechanism holding the door closed has indeed been electrically released allowing the door to open.
