12V DC Electromagnetic Cabinet Door Lock – Compact Solenoid Electric Deadbolt for Smart Lockers

Product Description The 12V DC Electromagnetic Cabinet Door Lock is a robust and compact electric deadbolt designed for high-security automated storage and access control. Built with a high-strength carbon steel body and a zinc-plated finish, this fail-secure solenoid lock ensures the door remains locked even during power failure. When a 12V pulse is applied, the internal electromagnetic coil retracts the bolt, allowing the cabinet or locker to open. Its slim profile and energy-efficient operation make it the ideal choice for smart vending machines, parcel lockers, electronic filing cabinets, and DIY biometric security projects.

Key Features

• Fail-Secure Mechanism: Ensures the cabinet remains locked during power outages, providing maximum security for valuable assets.

• Rapid Response Time: The electromagnetic solenoid triggers the deadbolt retraction in less than 1 second for instant access.

• Durable Steel Construction: Manufactured from high-quality carbon steel to resist mechanical stress, prying, and environmental wear.

• Universal Orientation: Features a symmetric design that allows the lock to be mounted for left, right, top, or bottom opening doors.

• Plug-and-Play Integration: Compact wiring design facilitates easy connection to relay modules, access controllers, and smart home systems.

Technical Details

• Operating Principle: Functions as a push-pull solenoid; the bolt is extended by a spring and retracted by electromagnetic force.

• Duty Cycle: Designed for intermittent operation (10% duty cycle); avoid keeping the solenoid energized for more than 10 consecutive seconds to prevent overheating.

• Surface Treatment: Zinc-plated surface provides excellent corrosion resistance and smooth mechanical movement.

• Mounting Pattern: Includes multiple M4 threaded holes for versatile mounting on wood, metal, or plastic surfaces.

• Power Requirement: Optimized for 12V DC; can operate briefly at 9V with reduced force or 14V with increased thermal monitoring.

• Lock Tongue Design: Features a beveled tongue to allow "slam-to-close" functionality without needing to energize the lock.

• Energy Efficiency: Consumes zero power in the locked state, making it perfect for battery-backed security systems.

• Impact Resistance: The internal plunger is designed to withstand vibrations and minor shocks without accidental unlocking.

• Cable Integrity: Equipped with high-temp PVC insulated wires, typically 20-25cm in length, with strain relief at the entry point.

• Compact Footprint: Miniature chassis allows installation in tight spaces where traditional electromagnetic locks cannot fit.

• Standard Compatibility: Works with standard 12V power adapters, UPS systems, and industrial access control panels.

• Internal Spring: High-elasticity spring ensures the bolt extends reliably and remains firmly in the locked position.

• Low Noise Operation: Precision-engineered mechanical parts minimize the clicking sound during actuation.

• Heat Dissipation: The steel frame acts as a heat sink for the copper coil during active cycles.

• Versatile Applications: Extensively used in smart city lockers, gym storage, automatic drawers, and medical equipment cabinets.
