12V Solenoid Door Lock Electromagnetic Cabinet Lock

DC12V Solenoid Electromagnetic Door Lock for Secure Cabinet Systems

The DC12V Solenoid Door Lock is a compact and reliable electromagnetic locking solution designed for modern electronic security systems. Widely used in cabinets, drawers, safes, and access-controlled doors, this lock operates on a fail-secure principle, meaning it remains locked when power is off and unlocks instantly when energized. This behavior makes it ideal for controlled environments where security is a priority.

Engineered for low power consumption and stable performance, this solenoid-based lock is suitable for DIY electronics projects, institutional security setups, and automation systems. At Bigyan Project and বিজ্ঞান প্রজেক্ট, this type of solenoid lock is commonly used in student projects, Arduino-based access control systems, and industrial training kits.
