Magnetic Torque-Limiting Shaft-to-Gear Couplings
Also known as hysteresis clutches, these couplings use magnetic force to brake, control tension, and prevent torque overload. They have few moving parts, so they last longer than mechanical couplings. Twist the adjustment ring to set the torque within the range listed, then lock the ring in place with the included set screw.

Electromagnetic Tensioning, Holding,
and Stopping Shaft-to-Gear Couplings
Also known as electric hysteresis brakes, these couplings use magnetic force to create drag to slow or stop the motion of your drive system. Use them with a current-limiting transformer to adjust the electrical current, which controls the amount of torque applied.

Electromagnetic Torque-Limiting Shaft-to-Gear Couplings
Use these with an overload sensor in an automated system to instantly disconnect power and prevent damage. Couplings also accelerate loads from zero to full speed in less than three milliseconds when the power is turned on.
