The 12V DC Solenoid Door Lock is an electrically controlled locking mechanism designed for access control and security applications. When powered, the solenoid actuates to lock or unlock the door, making it suitable for electronic door systems, smart locks, cabinets, and automation projects. Its simple operation and robust construction allow easy integration with controllers, relays, and access systems.
