Design Characteristics

Round and Rectangular Flat-Faced Electromagnets are available in a variety of sizes. Flat-faced electromagnets magnets should only be used on flat, smooth material where the entire magnet face is in contact. They can be used in manually operated or automated applications. Electromagnets are only magnetic when DC electric current is supplied. They are usually designed to hold parts directly, so their holding force is substantially reduced through small air gaps.

Common Applications
Holding sheet metal Lifting Pick and place use

Rectifiers / Controllers
Electromagnets require direct current power for operation. Variable power and remote control styles are available. Please inquire for your requirements. Another method of obtaining direct current for magnet operation is through use of 12 volt batteries.
