SOLENOID

Solenoids are electromechanical actuators that convert electrical energy into linear mechanical motion using an electromagnetic coil. This category includes a variety of DC solenoids such as push-pull solenoids, door lock solenoids, latch solenoids, and linear actuators used in automation, robotics, and control systems.

When an electric current passes through the coil, it generates a magnetic field that moves a plunger or rod, producing precise linear motion. This simple yet powerful mechanism makes solenoids ideal for switching, locking, pushing, and controlling mechanical systems.

Solenoids are widely used in Arduino, ESP8266, ESP32, and Raspberry Pi projects for applications such as smart door locks, vending machines, automated dispensers, robotics mechanisms, security systems, and industrial automation equipment. Their fast response time and reliable operation make them suitable for both DIY and professional applications.

Whether you are building a smart locking system, a robotics project, or an automated control device, solenoids provide a strong, efficient, and compact solution for controlled linear motion in modern electronic and mechanical systems.
