Description.......

These electromagnets have been expressly studied and realized for the field of machine tools, and for all the applications in which it is necessary to perform a linear shift.
They have a keeper sliding in a cylinder.
The keeper movement takes place from the initial to the final position by means of the electromagnetic force, while the return is operated by a different force, normally a spring.
The assembly position is irrelevant, but the power outlet must be set in the axial sense only, otherwise, in the presence of a side load, a considerable wear of the cylinder in which the keeper slides would occur.
These appliances consist of an electrical part and a mechanical part. The electric winding consists of a coil with free wires .
