Linear Solenoids and Pull Solenoids
Linear Solenoids or lifting solenoids are electromechanical magnets which generate (pull/push) a plunger in a straight line. Linear Solenoids consist of a case, a hollow coil, a plunger bearing and a plunger. The bearing and plunger should be free of friction and backlash to the extent possible.
Electric pull magnets
Electromagnets /pot magnets:
Electromagnets/pot magnets are electromagnets in a pot-form casing. With electromagnets/pot magnets, the coil and core are contained in a pot-like casing and are usually sealed with synthetic resin. The magnetic effect occurs when there is flat contact with the end face of the magnet at its highest point. This effect decreases with increasing distance.
Permanent magnets or lifting magnets which shut off electrically are pure electric magnets without any mechanical force transmission. The name electric pull magnet comes from their effect: (magnetisable) material cling to these magnets. The magnetic effect occurs when there is flat contact with the end face of the magnet at its highest point. This effect decreases with increasing distance.
