Magnetic ball joints
Steel ball magnetically held in spherical socket The steel ball is subject to a magnetic field in the permanent magnetic system and is thus held in the spherical socket by this magnetic force. This results in a joint which can be turned in any direction with an angle up to 180°. If the holding force of the magnet system is exceeded, the ball is released without damage
Application examples
Since the magnetic ball joint is electro-conductive, rapidrelease and rotatable electrical connections can be made with such a system. This is of advantage, for instance, in modern low-voltage lamps.
Rapid-release connections for test fixtures are also possible. In lifting linkages a predetermined breaking point can be provided, or sideways movements compensated. Due to the use of high-energy rare-earth magnets, magnetic ball joints types KD... have a very strong holding force. The resulting displacement force of the ball is strong enough to hold the optical systems of cameras, lighting fixtures or laser units without requiring a mechanical fixation. For magnetic ball joints with other dimensions please consult us for further information. Operating temperature:
