The SAC series features four models of pre-assembled, solenoid actuated, wrap spring clutch packages. SAC units operate from a single AC or DC pulse to accurately start loads at speeds up to 1800 rpm, depending on size. Adjustable stop control collars provide easy and accurate output stop position settings. A typical SAC series clutch will bring the load up to speed within 3 milliseconds. The SAC series is available in 4 sizes.
