Model 125 (Housing-Integrated Type_Clutch and Brake Unit)

This is a splash-proof electromagnetic clutch and brake unit that houses an electromagnetic clutch and an electromagnetic brake in a light alloy housing using a coaxial shaft configuration.Power is supplied via the input shaft and is constantly output via the output shaft. The output shaft is braked by energizing the brake when the clutch current is interrupted. Mounting brackets are available for selection.
