The DC 3–5V Smart Electromagnetic Lock (4-Wire Type) is a compact electronic locking mechanism designed for smart cabinets, lockers, drawers, vending machines, parcel boxes, and DIY access control systems. Operating from a low 3–5V DC supply, it is ideal for battery-powered and microcontroller-based projects.
- Red Wire: Connected to positive voltage (VCC, DC 3V to 5V).
- Black Wire: Connected to ground (GND).
- Two Signal Wires (often White/Yellow or Blue): Act as a built-in feedback switch to detect whether the door is open or closed. The loop bridges (closes) when the lock is securely engaged and disconnects when unlocked.
