Door Solenoid 12V 1A - JF-S0837DL

This door solenoid works with an electromagnet. The spring pushes the pin outwards by default, but the pin is pulled in when the solenoid is activated. This solenoid has no fixed polarity, so the voltage can be connected in two ways resulting in the same effect.

Note: Do not activate the solenoid for more than 10s at maximum voltage to prevent the coil in the lock from burning out. To keep the coil activated for a longer period of time, the current can be reduced to 20~30% right after the plunger has retracted (for example via PWM).
