DC 12V Electronic Cabinet Lock for Lockers, Mailboxes & Access Control
Upgrade your access control setup with this robust DC 12V electric cabinet lock. Built with a carbon steel interior and a steel plate shell finished with electrophoretic paint, this compact electromagnetic lock is engineered for long-lasting, dependable performance. Ideal for delivery lockers, refrigerated cabinets, mailboxes, newspaper boxes, self-service kiosks, book counters, changing-room cabinets, and more.
Key Features
- Heavy-Duty Construction: Carbon steel core and steel plate shell provide exceptional structural integrity and tamper resistance.
- High-Strength Latch Hook: Withstands up to 150 kg of traction force with no permanent deformation — shockproof and anti-prying for maximum security.
- Self-Elastic Spring Design: Adjustable spring push rod automatically opens doors with consistent thrust, suitable for doors weighing 0.5–5 kg.
- Flexible Installation: Compact form factor with no left/right/front/reverse orientation restriction. Supports a mechanical emergency-unlock position for added safety.
- Feedback Signal Output: Built-in short-circuit signal switch provides real-time lock status feedback — open circuit when unlocked, closed circuit when locked — making it easy to integrate with control systems.
- Power-Off Locking Mode: Lock engages automatically when power is off and the door is closed; applying power unlocks the latch.
- Wide Temperature Range: Operates reliably from -60°C to +70°C, suitable for refrigerated or outdoor environments.
- Outstanding Mechanical Life: Rated for approximately 500,000 cycles under design load; electromagnet rated for over 1,000,000 cycles at normal operating conditions.
- Corrosion-Resistant Finish: Electrophoretic paint coating passes a neutral salt-spray test of over 500 hours.

Frequently Asked Questions
Q: What type of doors or cabinets is this DC 12V electric lock compatible with?
A: This electronic cabinet lock is designed for a wide range of lightweight cabinet doors, including delivery lockers, refrigerated cabinets, mailboxes, newspaper boxes, self-service kiosks, book counters, and changing-room lockers. It works best with doors weighing between 0.5 and 5 kg.
Q: Does this lock require a specific mounting orientation?
A: No — one of the standout features of this electric lock is its orientation-free installation. There are no left, right, front, or reverse mounting restrictions, making it highly flexible for various cabinet configurations. It also supports a mechanical emergency-unlock position.
Q: How does the power-off mode work for this electronic lock?
A: This lock operates in a "fail-secure" mode: when power is off and the door is closed, the lock automatically engages. When DC 12V power is applied, the electromagnetic mechanism retracts and unlocks the door. This makes it suitable for access control systems where security must be maintained during power outages.
Q: What does the feedback signal output do?
A: The feedback signal line is a short-circuit switch that reports the real-time status of the lock to a connected control system. The circuit is open (disconnected) when the lock is in the unlocked state and closed (connected) when it is locked, allowing easy monitoring and integration with access control panels or automation systems.
