12V Solenoid Electric Door Lock Catch – Access Control Release
12V Solenoid Electric Door Lock Catch – Access Control Release Assembly
Upgrade your door or gate security with this compact and reliable 12V DC Solenoid Electric Door Lock Catch. Designed for seamless integration into access control systems, this electronic latch lock uses an interrupted-power mechanism — energize to unlock, de-energize to lock — making it ideal for automated gates, cabinet doors, office entry systems, and more. Made in Mainland China.
Key Features
- Simple Wiring: Red wire to positive, green wire to negative — quick and straightforward installation with no polarity confusion.
- Spring-Loaded Locking: When power is OFF, the internal spring extends the lock tongue 4.4mm to secure the door. When power is ON, the tongue retracts 4.4mm to release the door.
- Fast Unlock Response: Unlocks in approximately 1 second upon power activation for smooth, responsive operation.
- Compact & Versatile: Slim form factor fits a wide variety of residential and commercial door and gate applications.
- Interrupted Power Form: Operates in an interrupted mode, ensuring the door remains locked in a power-off state for added security (fail-secure design).
- Low Power Draw: Runs on DC 12V / 0.4A — energy-efficient and compatible with most standard access control power supplies.

Frequently Asked Questions
Q: Is this solenoid door lock fail-secure or fail-safe?
A: This 12V solenoid door lock operates in fail-secure (interrupted) mode. That means the lock tongue is extended and the door remains locked when power is OFF. Power must be applied to retract the tongue and release the door, making it a secure default state for most access control applications.
Q: What power supply do I need for this electric door lock catch?
A: This solenoid lock requires a DC 12V power supply capable of delivering at least 0.4A. A standard 12V DC access control power supply or adapter is compatible. Ensure your power supply is stable and regulated for optimal performance.
Q: Can this solenoid lock be used outdoors or on a gate?
A: Yes, this electric lock catch is suitable for use on gates and doors in sheltered or semi-exposed environments. For fully outdoor or weather-exposed installations, it is recommended to protect the unit with an appropriate weatherproof housing to ensure longevity.
Q: How difficult is the installation of this access control lock?
A: Installation is straightforward. Simply connect the red wire to the positive terminal and the green wire to the negative terminal of a DC 12V supply, mount the lock body, and align the catch plate. Basic DIY skills and common hand tools are sufficient for most installations.
