Adafruit Small Push-Pull Solenoid - 12VDC

Solenoids function as efficient electromagnets comprised of a copper wire coil with an armature at their core. Upon energizing the coil, the armature is drawn inwards, enabling push and pull actions. This compact solenoid features a 30mm body and a captive armature equipped with a return spring. Activating with up to 12VDC causes movement, and deactivating lets it spring back, providing versatile utility absent in many low-cost types.Enhancing its functionality, this solenoid includes convenient mounting tabs. For optimal performance, utilize a power transistor and a diode, especially if integrating with microcontrollers like Arduino. Be mindful of its 250mA power demand, avoiding 9V batteries for operation.
