Abstract
A magnetic gripper for gripping a ferromagnetic workpiece, having: a housing; a magnet arranged in the housing and displaceable along a displacement direction between a gripping position for gripping the ferromagnetic workpiece and a release position for releasing the ferromagnetic workpiece; and a number of pole shoes fastened to the housing. Each pole shoe has a workpiece contact surface and is designed to guide a magnetic field portion of the magnet to the workpiece contact surface. Each workpiece contact surface defines a contact surface angle between itself and the displacement direction. The contact surface angle ranges in size from 170° to 190°.
