   A
solenoid is a device designed to convert
electrical energy into linear work:
this can be either push or pull.The moving part of the solenoid is called the plunger and it is the movement of the plunger which is expressed as the stroke, measured in millimetres. The Force/Stroke graphs shown with each type of solenoid give the nominal force, measured in N (or kg) that will be available from the plunger at any particular plunger position. The Duty Cycle of a solenoid is the ratio of ON time to the total time for one cycle of operation and is expressed as a percentage, for example:
A 100% rated Duty Cycle solenoid means that it has continuous rating and can therefore be left on continuously energised without overheating. Solenoids can be either AC or DC. In general, AC solenoids are more powerful and faster than DC but they are not as quiet and the plunger must not be prevented from fully closing as it will quickly overheat. Most of the solenoids shown in our catalogue section can be modified to suit your application. However, we also supply a range of specialist solenoids such as latching, bi-stable, clapper and rotary, etc.
