The miniature SK2 safety couplings have an accuracy of overload release torque of +/- 5%, even with 14 oz-in. of torque. Each coupling’s outside diameter is just under 3/4 in. for most of its length, and its largest diameter is less than 1 in. at the location of the actuation ring. This ring moves axially at overload release, and a proximity sensor can detect it to signal the drive to shut down.
