Adafruit Medium Push-Pull Solenoid - 5V or 6V

Solenoids function as dynamic electromagnets, featuring a robust coil of copper wire surrounding a metal armature. When activated, this armature is drawn into the coil's center, allowing the solenoid to either pull from one end or push from the other.

This specific solenoid distinguishes itself with a sturdy 27mm body and a 10mm throw. Its captive armature, coupled with a return spring, ensures that when powered with up to 6VDC, the armature moves, then resets to its initial position upon de-energization. This functionality is frequently absent in more economical push-only or pull-only solenoids without return springs.

Requiring a supply of 5 to 6VDC, this solenoid transforms into a potent magnet when electrified. Deactivation returns it to its original metal state. Given its coil structure, utilizing a motor or solenoid driver equipped with kick-back protection is crucial. It necessitates a strong driver due to a 5V current draw of 800mA, escalating to 1 Amp at 6V. Compatible with Crickit boards when using a motor port, it demands a power transistor and a diode for operation with microcontrollers, like Arduino.
