SAC Clutch Series

SAC Clutch Series

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. They are easy to interface with PCs and industrial control systems. SAC Series clutches are accurate, repeatable, fast acting, simple, maintenance free, and low cost.
