Here you will find our range of easy-to-use electromagnets. These energize-to-hold magnets are also commonly known as solenoids and are available in a range of sizes from 25/32" to 1 31/32" diameter. These electro-holding magnets, as their name suggests, become magnetized when an electric current is applied. This magnetic field then completely disappears when the power is switched off. Every magnet is supplied pre-wired for attaching to a power source (not supplied); common applications for these electromagnets include access control on fire and security doors and hatches, machine guards, automated assembly lines, robotics. If you require any advice about the application of electromagnets, please call our technical sales team today on 800-917-0841.
