12V Solenoid Door Lock

12 V Solenoid Door Lock – Actuators & Prototyping
The 12 V Solenoid Door Lock is a compact, electromechanical actuator that converts an electrical signal into a reliable linear pulling force, perfect for securing or releasing a latch in a miniature door, cabinet, or robot chassis. Designed for easy integration with Arduino, Raspberry Pi, or any 5 V‑12 V control board, the lock features a built‑in diode for fly‑back protection and screw terminals for quick wiring. In the classroom, students use this module to explore the fundamentals of electromagnetism, circuit design, and real‑world security mechanisms.

What students will learn & why it shines in STEAM

• Science: How magnetic fields are generated by current and how they create mechanical motion.
• Technology: Interfacing the lock with micro‑controllers, PWM control, and protective circuitry.
• Engineering: Designing latch mechanisms, stress testing, and troubleshooting power‑draw issues.
• Art & Design: Incorporating the lock into interactive installations, escape‑room props, or kinetic sculptures.
• Mathematics: Calculating force, energy consumption, and timing curves for precise actuation.

Key Features

• 12 V nominal voltage, 0.8 A peak current (compatible with most hobby power supplies)
• 10 mm stroke with up to 6 kg pulling force
• Integrated fly‑back diode and reverse‑polarity protection
• Compact 30 mm × 20 mm housing, mounting holes for easy chassis integration
• Comes with a 100 mm lead wire, screw terminals, and a PDF of example code

Because it bridges theory and hands‑on creation, the 12 V Solenoid Door Lock is an ideal platform for STEAM projects—from automated lockers and smart pet feeders to robotic grippers and interactive art pieces—giving students a tangible way to see physics, coding, and design work together.
