Electromagnetic clutch/brake

    Effective as an actuator during unwinding/winding of long materials

    Mitsubishi Electric electromagnetic clutch and brake units are precision tension control components built for industrial winding and unwinding applications. Unlike friction-based clutches and brakes, Mitsubishi Electric's powder clutch and powder brake range uses magnetic iron powder as the torque transmission medium delivering smooth, continuously variable torque control that friction systems cannot achieve. The result is stable, repeatable tension control across the full operating speed range, from standstill to high-speed production. DahebTech is an officially authorised Mitsubishi Electric dealer in the UAE, supplying the complete ZKB and ZKG electromagnetic clutch and brake range to industrial clients across all sectors. Every unit we supply is genuine, certified, and backed by full manufacturer warranty. Whether you are specifying a new tension control system or sourcing a replacement unit for an existing installation, our technical team provides selection guidance and reliable supply across the UAE.

    Mitsubishi Electromagnetic Clutch Brake UAE

    A powder clutch ( ZKB-BN or ZKG-AN series ) is used on the winding side of a process it connects the motor drive to the winding reel and controls the torque applied to wind material onto the reel. A powder brake ( ZKB-XN or ZKG-YN series ) is used on the unwinding side it applies a controlled braking torque to the let-off reel to maintain back tension as the material unwinds. In a complete winding system, a powder clutch and powder brake are typically used together the brake on the unwind stand, the clutch on the rewind stand.
    The ZKB series (ZKB-BN powder clutch, ZKB-XN powder brake) is the standard industrial range, covering medium to heavy duty torque requirements across a wide range of torque ratings. The ZKG series (ZKG-AN micro powder clutch, ZKG-YN micro powder brake) is the compact micro range designed for light to medium duty applications where a smaller physical footprint is required. Both series use the same magnetic iron powder torque transmission principle and offer the same smooth, continuously variable control characteristics. Selection is based primarily on the required torque rating and available installation space.
    Yes. Mitsubishi powder clutches are well suited to torque limiter applications, where the clutch is set to slip when the transmitted torque exceeds a defined limit — protecting downstream machinery from damage caused by mechanical overload. The continuously adjustable torque characteristic makes it straightforward to set the slip point accurately. This application is common in conveyors, packaging machinery, and production lines where jam protection is required.

Our technical team can assist with series selection and torque sizing for your specific application.
    Mitsubishi Electric ZKB and ZKG series powder clutches and brakes are typically excited by a DC power supply. The standard excitation voltage is DC 24V on most models, with excitation current varying by torque rating. An appropriate DC power controller or tension controller is used to regulate the excitation current and therefore the transmitted torque. DahebTech can advise on compatible tension controllers and power supplies for your specific unit and application.
