Solenoids are components or pieces that have an electric coil wrapped around a metal case to create a magnetic effect as the current passes through the coil. These electrical solenoids also have a plunger or shaft to move when an electric current passes through the coil.

Solenoids are available in two broad categories: rotary solenoids and linear solenoids. Rotary solenoids are useful for equipment such as machine tools, laser devices and medical instruments. Linear solenoids are useful for devices such as vending machines, door locks and circuit breakers. Electrical solenoids are actuators as they start an activity or motion. Solenoids are useful for various equipment such as measuring instruments, industrial machinery and medical devices.

Some important parameters you must consider before you buy solenoids are:

1. Pressure, force and temperature at which the solenoids will work
2. The current or the power required by solenoids
3. The operating time and speed at which the solenoids will work
4. Expected useful life of solenoids

Buy solenoids from reliable solenoids manufacturers

Once you have the information about solenoids manufacturers and the type of solenoids they offer, go to the specific solenoids manufacturer that offers solenoids suitable for your applications.

I recommend: You can buy a variety of solenoids and solenoid actuators at Magnet-Schultz of America, a manufacturer of standard and custom solenoids. Ledex is another manufacturer that sells different types of linear solenoids, electric solenoids, solenoid actuators and tubular solenoids. You can buy a transmission solenoid at BorgWarner, a manufacturer of fuel injection solenoids and pneumatic suspension control devices.

Buy solenoids from reliable solenoids distributors

You can compare different industrial solenoids based on the features and prices at distributors or retailers' websites.

I recommend: You can buy solenoid valve at W.W. Grainger, an industrial distributor. You can also buy an air solenoid at Ryder Fleet Products, a distributor of solenoids and relays. Jamieson Equipment Company is another distributor that sells different types of solenoids.

Buy custom solenoids from reliable manufacturers of custom solenoids

If the standard solenoids do not meet your requirements, you can ask reputable solenoid manufacturers to provide customized solenoids.

I recommend: Deltrol Controls, a manufacturer of speciality solenoids, supplies solenoids as per customers’ requirements. Autotronics is another reputable custom manufacturer of solenoids and accessories. You can also buy a customized rotary solenoid at G.W. Lisk Company, a manufacturer of solenoids.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Select the bearing system carefully, as it has direct impact on the useful life of solenoids.
• •  If the solenoid temperature is rising unexpectedly, consult an expert or use a cooling fan.
