Key Features
- 12V DC Operation: Standard voltage compatible with most power supplies, batteries, and microcontroller relay modules.
- Fail-Secure Design: The bolt remains extended (locked) when power is off and retracts (unlocks) when 12V is applied - ensuring security during power outages.
- Spring-Return Mechanism: Built-in return spring automatically re-extends the bolt when power is removed, providing reliable locking without continuous power.
- Quick Response: Sub-half-second actuation time for near-instant locking and unlocking.
- Compact & Lightweight: Small form factor fits easily into door frames, cabinets, drawers, lockers, and custom enclosures.
- Easy Wiring: Simple 2-wire connection - just supply 12V DC through a relay, MOSFET, or transistor driver circuit.
- Microcontroller Friendly: Drive it with Arduino, ESP32, or Raspberry Pi using a relay module, TIP120 transistor, or IRF540N MOSFET with a flyback diode for protection.
- Durable Metal Construction: Sturdy metal housing and hardened plunger bolt built for repeated actuation cycles.
- Screw-Mount Installation: Standard mounting holes for quick and secure installation on wood, metal, or plastic surfaces.
Why Choose This 12V DC Solenoid Lock?
- 100% authentic solenoid from trusted suppliers - tested and verified before dispatch.
- 1-5 day shipping, 7-8 day delivery across India from our Bengaluru warehouse; same-day delivery available in Bengaluru.
- Expert technical support included - get help with wiring, driver circuits, and integration into your project.
- Widely used and well-documented - extensive community tutorials and code examples available for Arduino and ESP32.
- Affordable and reliable solution for both DIY hobbyists and professional security installations.
How It Works
This solenoid lock operates on a simple electromagnetic principle. When 12V DC is applied to the coil, a magnetic field is generated that pulls the metal plunger (bolt) inward against the spring, retracting it and unlocking the door. When power is removed, the internal spring pushes the bolt back out into the locked (extended) position. This fail-secure behavior means the lock stays locked even during power failures.
Important: Since the solenoid coil is an inductive load, always use a flyback diode (such as 1N4007) across the solenoid terminals to protect your driver transistor, MOSFET, or relay from voltage spikes when the solenoid is de-energized.
Typical Wiring Guide
- With Relay Module (Recommended for Beginners): Connect the Arduino/ESP32 digital pin to the relay module input. Connect the solenoid's two wires to the relay's NO (Normally Open) and COM terminals. Supply 12V DC to COM through the relay. When the microcontroller sends a HIGH signal, the relay closes and the solenoid unlocks.
- With MOSFET/Transistor Driver: Use an N-channel MOSFET (e.g., IRF540N) or NPN transistor (e.g., TIP120). Connect the gate/base to the microcontroller pin via a resistor. Connect the solenoid between 12V supply and the MOSFET drain. Place a 1N4007
