Permanent Electro Holding Magnets

Permanent electro holding magnets consist of a permanent magnet that is installed into a magnet housing together with an excitation coil. The magnetic circuit, which is open in the switched-off state, allows for currentless and safe holding of magnetic workpieces. When the DC-excited coil is switched on, the permanent-magnetic field is neutralized at the holding surface, and the workpiece to be held can be taken off. These magnetic systems are very energy-efficient as the magnet is only briefly energized to release the workpiece. They are used in particular if there are long holding times without energy consumption and where loads must be reliably and safely held in case of power failure.

Kendrion offers the following standard models:

Series 01 320: Permanent (electro) holding magnets in a round design with a diameter of 20-150mm

Series 01 310: Permanent (electro) holding magnets in rectangular design in lengths of 150 and 200mm

Series PEM: Permanent (electro) holding magnets in a round design with a diameter of 12-25mm. A threaded rod at the rear side is available for installation.

GTN Series – now even more powerful: The new generation of our permanent electro holding magnets impresses with its optimized design, which enables maximum holding force without power in the smallest of spaces. The round electromagnets of the GTN series are IP65-rated and therefore ideal for demanding applications. In standard sizes of 25, 35, and 50 mm diameter, they achieve impressive holding forces of 120, 300, and 700 N, respectively, with a duty cycle of 40%.

The magnets achieve the maximum holding forces possible if the armature plate rests directly and to the full extent on the surface. The holding forces reach from 8-3,500 N.
