TAU-0420 Electromagnetic Lock Linear Solenoid DC 6V
6V Electric Lock for Access Control Systems
The TAU-0420 is a DC 6V electromagnetic linear solenoid lock designed for reliable locking in access control systems, cabinets, and automation projects. It draws 0.85A to 1.8A and provides strong holding force for various security applications.
6V DC Operation Compatible with lowvoltage control systems
High Current Draw - 0.85A to 1.8A for strong magnetic engagement
Operating voltage is DC 6V with current draw 0.85A to 1.8A
Magnetic locks generally release when power is cut (fail-safe)
Avoid energizing the coil for extended periods (under 5s recommended to prevent overheating)

Connection and Usage
Power connection:
- Connect to DC 6V power supply
- Polarity does not affect operation
- Use appropriate wire gauge for 0.85A to 1.8A current draw
Operation principle:
- Lock engages when powered
- Releases when power is removed
- Instant unlocking for quick access
Use a relay or transistor to control the lock from Arduino
Add a flyback diode across the solenoid to protect circuits
Do not energize continuously for more than a few seconds
Troubleshooting
Lock not holding:
- Verify 6V power supply
- Check current draw (0.85A to 1.8A)
- Ensure proper alignment with armature plate
Excessive heating:
- Reduce energizing time
- Use lower duty cycle operation
- Check for correct voltage supply
Door not locking:
- Ensure armature and electromagnet contact fully
- Remove debris from contact surfaces
- Verify mounting is secure and aligned
