HLA DC holding magnet

Holding Magnets are pot magnets and consist of a magnet housing and a DC excited coil.

These are DC holding solenoids, which are shielded solenoids with an open magnetic circuit, which allows the system to adhere to ferromagnetic objects when activated. The coil is encapsulated with cast resin (IP65 protection). The complete magnet housing including holding surface is galvanized. This increases the holding forces by approx. For devices with a bare pole surface, the holding force  is approx. 10% lower. The magnets are attached via a central thread on the back of the housing.

The magnetic circuit, which is open when switched on, enables ferromagnetic workpieces to be held or clamped. When the applied voltage is switched off, the workpiece to be held falls off. Remanences can be avoided by sticking on a non-magnetic foil.
