The DC 12V Solenoid Electromagnetic Door Lock is a compact, high-reliability locking mechanism designed for automated security systems. At Electrapac, we recommend this mini solenoid lock for anyone building smart cabinets, secure drawers, or Arduino-based access control systems.

Product Overview

This electromagnetic lock operates on a simple "Power-to-Unlock" principle (Fail-Secure). When 12V DC is applied, the internal coil creates a magnetic field that pulls the bolt back, allowing the door or drawer to open. When power is removed, a heavy-duty spring pushes the bolt back out into the locking position. Its small form factor makes it ideal for tight spaces where traditional bulky door locks won't fit.

Key Features for Electrapac Customers

• Instant Response: The solenoid reacts in milliseconds, providing snappy and reliable unlocking for quick-access applications.

• Low Profile Design: The ultra-slim body allows it to be hidden inside drawers, jewelry boxes, or small lockers without taking up storage space.

• Fail-Secure Safety: In the event of a power failure, the lock remains in the Locked state, ensuring your valuables stay protected.

• Easy Installation: The chassis features multiple pre-drilled mounting holes, allowing for vertical or horizontal mounting on wood, metal, or plastic surfaces.

• Versatile Orientation: The triangular bolt can be rotated 90, 180, or 270 degrees by removing a single clip, allowing it to work with doors opening in any direction.

Wiring & Safety Tip

Because this is an inductive load, it requires specific handling when connecting to microcontrollers from www.electrapac.com:

1. Driver Circuit: Do not connect the lock directly to an Arduino pin. Use a Relay Module or a TIP120 Transistor to handle the 12V current.

2. Flyback Diode: Always use a diode (like the 1N4007) across the lock terminals to prevent voltage spikes from damaging your electronics when the lock is switched off.

3. Duty Cycle: This lock is designed for "momentary" use. Avoid keeping it powered for more than 10 seconds at a time to prevent the internal coil from overheating.

Primary Applications

• Smart Lockers: Creating a PIN-code or RFID-operated locker for gyms or offices.

• Automated Drawers: Hidden "secret" drawers that open via a hidden switch or smartphone app.

• Vending Machines: Securing small product dispensing compartments.

• Key Cabinets: Managing access to physical keys in an industrial environment.

• Home Security: Adding an extra layer of digital protection to cupboards or pantry doors.
