Description.......
This
type of electromagnets has been expressly studied
and realized for the control of oleodynamic valves.
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 reverse motion 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 waterproof mechanical part.
The electrical winding is costituted by a coil encapsulated
with the connector electrical contacts complying with
DIN 43650.
