Adafruit Mini Push-Pull Solenoid - 5V

Solenoids operate as electromagnets, utilizing a coil of copper wire and a central armature. Energizing the coil activates the solenoid, moving the armature inward. This specific solenoid is compact with a 20mm body and includes a captive armature featuring a return spring, allowing it to move effectively at ~5VDC and return to its original position upon deactivation.Common solenoids often lack versatility, but this model pushes and pulls efficiently. The inclusion of mounting tabs enhances its versatility. To operate, a power transistor and a protection diode are required, and wiring it to a microcontroller, like an Arduino, is straightforward when following the proper diagram.Finally, be mindful of its power demands as solenoids require significant current, approximately 1 Amp, to engage the electromagnet. Avoid using a computer's USB to power it, opting for a robust power supply to ensure efficient operation.
