For contactless torque transmission in other media [through walls]
Permanent magnet clutches consist of opposing discs that are equipped with very strong rare earth magnets. The torque, which then acts on one of the discs, is automatically transferred to the other disc over the gap.

Torque transmission via flat vessel walls or similar is thus easily possible. Due to the simple, flat construction, an angular error of up to 3° and a parallel offset of up to 6 mm can be accepted. Nearly the entire torque is then still transferred.These two-part permanent magnet clutches ensure non-contact torque transmission through all kinds of walls.Examples of usage:
