Browse Solenoids by type

In its simplest terms, a solenoid is a device that converts electrical energy into mechanical movement.

A solenoid, constructed from copper wire which is uniformly wound onto a spool to create an electrical coil, generates a controlled magnetic field when an electrical current is applied. The magnetic field interacts with a ferromagnetic armature positioned inside the hollow core of the spool which converts the electrical current into fast linear or rotary shaft motion.

Rotary, linear, and holding solenoids are found in a wide variety of industrial applications; these include medical, automotive, machine automation, wind energy, marine and agricultural applications.

  • Rotary solenoids provide fast pivotal movement to a predefined angular position of 25°, 35°, 45°, 65° and 95° when powered.
  • Linear solenoids develop force in a linear direction when energised, stroke lengths of up 40mm are possible with the largest solenoid.
  • Holding solenoids are solenoids without moving parts; they attract ferromagnetic material when powered.

Typical examples of application use include door locks, oxygen mask release mechanisms, gearbox interlocks, cash dispensing machines, amusement arcades, printers, laser positioning, parking ticket machines, card readers, conveyor feeds and diverters.

The majority of applications call for a solenoid which is unique in some way without requiring significant engineering. The duty cycle or operating voltage, the mounting, the return spring, the plunger end design, the electrical connections and insulation can be specified to suit the customer.

A solenoid manufacturer should be able to provide the right product for a given application quickly and cost-effective where possible; this is done by utilising a standard design and adapting it.
