CB Series combination clutches and brakes accurately start and stop loads driven by a continuously rotating power source. CB units operate from a single AC or DC pulse, stopping the load within ±½° noncumulative at speeds up to 1800 RPM, depending on size. Adjustable control collars for easy and accurate output stop position setting. Load over-travel or back-up is eliminated since CB units lock the load in both directions when the solenoid is off. Permanently lubricated—never needs adjustment for wear. Brings load up to speed in 3 milliseconds and stops within 1.5 milliseconds. RoHS compliant.
