Electromagnetic toothed Clutch

Electromagnetic clutches and brakes are control components that use electromagnetic force to instantly engage, disengage, and stop rotational power. Our lineup includes clutches to transmit power and brakes to stop and hold rotation. We offer a wide range of products, including compact tooth clutches that deliver exceptionally high torque, and spring actuated electromagnetic brakes that stop using only friction when power is disconnected.
