Product Description (Detailed):

Enhance the security and automation of your projects with our 12V DC Solenoid Door Lock. This compact electronic lock is an ideal solution for a wide range of applications, including securing cabinets, drawers, lockers, and integrating into sophisticated access control systems. Its small footprint and robust electromechanical design make it a versatile choice for both professional installations and DIY smart home projects.

Operating on a standard 12V DC supply, this solenoid lock functions on the principle of electromagnetism. Inside, a coil of wire (the solenoid) is energized, which pulls a metal slug or plunger (the armature) into its core. This action either retracts or extends a bolt, thereby locking or unlocking the mechanism. Many of these locks are "fail-secure," meaning they remain locked when power is removed, providing an added layer of security during power outages. Conversely, "fail-safe" models unlock when power is lost, which is useful for emergency exits. (Please check the specific product description for the exact operational mode).

This miniature solenoid lock is renowned for its quick response time and straightforward integration. It typically requires only a simple 12V DC power source and can be easily controlled by microcontrollers like Arduino, Raspberry Pi, or ESP32 via a relay or a power transistor. This enables you to build custom access control solutions using keypads, RFID readers, fingerprint sensors, or even remote commands over Wi-Fi or Bluetooth.

Common applications for our 12V DC Solenoid Door Lock include:

• Smart Cabinets & Drawers: Secure personal belongings, tools, or sensitive documents.

• Electronic Lockers: Implement automated locker systems in gyms, schools, or workplaces.

• Vending Machines: Control access to product compartments.

• Automated Doors & Gates: Ideal for smaller, lightweight doors where precise electronic control is needed.

• Custom DIY Security Projects: Create intelligent pet feeders, secure display cases, or hidden compartments.

With its durable construction and reliable performance, this compact electronic lock offers a practical and effective way to add automated security to your designs.

The 12V DC Small Solenoid Lock is a compact, electronic locking mechanism ideal for cabinet doors, drawers, lockers, and custom security systems. When power is applied, the solenoid’s internal plunger retracts, unlocking the latch. When power is removed, a spring returns the plunger to the locked position.

This lock is perfect for DIY smart lock systems, vending machines, automated lockers, or RFID/NFC access control. Compatible with Arduino, ESP32, Raspberry Pi, and relay modules, it's an essential component for anyone building automated or IoT-enabled lock systems.

How to Use:

Basic Operation:

1. Connect the solenoid lock's wires to a 12V DC power supply (red = +12V, black = GND).

2. When power is ON, the latch retracts (unlocks).

3. When power is OFF, the spring-loaded latch returns to the locked position.

For Smart Control (with Arduino):

• Use a relay module or transistor (e.g., TIP120) to switch the 12V supply via a microcontroller.

• Combine with RFID, fingerprint sensor, keypad, or mobile app for access control.

Applications:

• Smart door locks for cabinets and drawers

• Automated lockers and storage boxes

• Access control systems (RFID, fingerprint, NFC)

• DIY vending machines and kiosks

• Arduino/ESP32/IoT security projects

• ATM & payment kiosk security

Package Includes:

• 1 × 12V DC Small Solenoid Lock

• (Mounting screws optional, depends on supplier)
