Electronic access control systems rely on precise electromechanical components to ensure secure, reliable, and responsive operation across residential, commercial, and industrial environments. For OEMs, devices such as D-frame solenoids, C-frame solenoids, tubular solenoids, magnetic latching solenoids, relays, buzzers, and clappers provide the actuation, switching, and signaling functions that make modern access systems both secure and user friendly.
Solenoids are central to physical locking and movement within access control hardware. D frame and C frame solenoids offer compact, fast acting linear motion ideal for door strikes, cabinet locks, and small electromechanical latches. Their responsiveness ensures doors unlock or secure instantly when triggered by a credential reader or control panel. Tubular solenoids deliver higher force and smoother motion, making them well suited for heavy duty locks, reinforced access points, and automated barriers. Magnetic latching solenoids add energy efficiency benefits by maintaining their position without continuous power—an essential feature for battery powered or low energy systems such as smart locks, wireless access devices, and remote controlled security enclosures.
Across electronic access control, these components enable precise actuation, dependable switching, and intuitive signaling. They empower OEMs to build systems that deliver long term reliability, enhanced security, and seamless user experiences in high end residential, commercial, and mission critical environments.
Deltrol Controls supplies solenoids and custom assemblies to the security industry which can be found in commercial electronic door locks, gate locks, controlled access storage cabinets, Smart lockers, and many more applications. They are primarily used to lock or unlock doors, trigger alarms or indicators, and interface between different systems like automatic doors, intercoms, and fire alarms. Most products are custom designed for specific application requirements. Many of our products have UL certification.

Linear Solenoid Actuators
Deltrol Controls linear solenoids are available in both AC and DC coil voltages, pull or push style. We offer D-frame, C-frame, tubular, and magnetic latching designs. In physical access control systems, solenoids are often used as actuators in door locks, latches, and release mechanisms.
Relays
Relays switch power to locking mechanisms, manage door held open timers, control alarm circuits, and isolate sensitive electronics from high voltage loads. Their reliability is critical in systems that must perform flawlessly during thousands of daily cycles. Deltrol Controls offers one of the most extensive power relay product lines in the industry.
Buzzers & Clappers
Audible signaling devices—buzzers and clappers—enhance safety and user awareness. Buzzers provide clear alerts for unauthorized access attempts, door ajar conditions, or emergency egress events. Clappers, with their distinct mechanical sound, are often used in industrial or high noise environments where audible clarity is essential. Together, these devices help ensure users and security personnel receive immediate feedback during critical moments.
