Solenoid Fundamentals

Solenoids are electromechanical devices that convert electrical energy into mechanical motion to perform work. They consist of a coil, an iron containment body and a plunger. This document provides information on solenoids that produce mechanical linear motion. While all linear solenoids are basically pull type, they can also push when equipped with a rod mounted on the inner end of the plunger. After the coil is de-energized, the weight of the load acted upon, or a spring, will cause the return motion.

Some of Our Many Industry Leading of Capabilities

  • Magnetically efficient solenoids
  • Stopless solenoids with reduced parts and greatly reduced cost
  • Frameless solenoids
  • The smallest, tubular Interposer solenoids available
  • Magnetically Latching
  • Mechanical latching solenoids
  • TRICORE tubular solenoids with reduced electrical power requirements for battery operation -- they are also physically interchangeable with industry standard tubular for example 3/8", 3/4"diameters
  • "Smart Solenoids" able to handle variable input voltages, pulse width modulation and power-down/hold-in circuits
