Holding magnets with electrical switch-off

The permanent magnet system of these holding magnets creates a magnetic field between the centre pole and the outer border of the holding surface. In addition to the permanent magnet, which creates the holding force, a coil is installed. When 24 V= is applied to this switch-off coil a counterpole magnetic field is set up to neutralise the permanent magnetic field. As a result workpieces can easily be removed. These holding magnets will preferably be used when long-term holding times are required and tools should be loosened by switching on the coil for a short period.
PRODUCT DESCRIPTION

Installation: Fixing by inner thread on the reverse side. Observe the thread depth. When installing flush in steel a case made of non-magnetisable material (e.g. brass) is required, or the holding area has to project from the surface (thickness of the case wall or projection corresponding to the thickness of the outer pole).

Turning-on duration: The holding magnets are made for 25 % TD at a duration of = 2 min. or 40 % TD at = 0.5 min. In maintaining the turning-on duration the remaining holding force amounts to max. 3 % of the nominal force.

You can increase the holding force by reversing of the electric polarity and switching on the coil for a short period
