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.

Specifications:

Voltage: 12V DC
Current: ~1A at 12V (only for short-term use (10s))
Current (max for long-term use): 300mA (current must be regulated back yourself, this is possible with PWM for example)
Force: 15N
Stroke length: 10mm
Dimensions (frame): 51 x 20 x 26mm (width can deviate slightly due to the coil windings)
Dimensions (with door latch): 65 x 20 x 26mm
Has four mounting holes with M3 threads
Cable length: ~ 20cm
This solenoid has no fixed polarity, so the voltage can be connected in two ways resulting in the same effect.

Note: We do not recommend activating the solenoid for a long time. This solenoid is intended for short-term use.
