Solenoid / Magnetic Coil: Voltage 12V DC to 240V AC

Component Specifications

Definition

A solenoid or magnetic coil is an electromechanical component that converts electrical energy into linear mechanical motion through electromagnetic induction. In trip mechanisms, it serves as the primary actuator for emergency or controlled disengagement of mechanical systems, providing rapid response and precise control.

Working Principle

When electrical current flows through the coiled conductor, it generates a magnetic field that attracts or repels a ferromagnetic plunger or armature, creating linear motion. This motion is used to trigger mechanical linkages in trip mechanisms.

Materials

Copper or aluminum winding wire (typically 18-24 AWG), steel or iron core, insulating materials (Class B, F, or H), epoxy encapsulation, protective housing (stainless steel or engineered plastic).
