Product Description:

The 06.09.670 is an electromagnetic clutch-brake unit produced by KEB within the Combibox Clutch Brakes series. It is installed between a driving motor and the driven load so that motion can be rapidly connected or stopped under PLC control in conveyors, indexing tables, and similar automated stations. The device relies on a DC-energized magnetic field to transmit torque through friction plates, providing precise start-stop cycles without external hydraulics or pneumatics, and it mounts directly through standardized B14 and B5 flanges to simplify installation in compact machine frames.

The coil is energized at 24 V DC and draws 15 W, so the unit can operate from common 24 V control supplies. When voltage is applied, the clutch engages within 55 ms; when power is removed, it releases in 15 ms after a delay of 18 ms, which helps keep cycle timing predictable for synchronous indexing. Under continuous duty, the friction package transmits a rated torque of 7 Nm, and rotational speeds up to 3000 rpm are permitted without exceeding surface velocity limits. This combination suits machines that need coordinated motion with fast response and controlled stopping.

During repetitive stops, the linings dissipate a maximum energy of 1.9 × 10³ J per cycle and a steady thermal load of 81 J/s, which helps prevent fade in high-duty operation. The moving components add little inertia, with only 0.80 × 10⁻⁴ kg·m² on the armature and 1.07 × 10⁻⁴ kg·m² on the rotor, so the driven axis can accelerate quickly with minimal added load on the motor. Correct clearance is maintained by a 0.2 mm rated air gap, and nominal force can be restored once wear reaches the 0.4 mm readjust gap. A B14 input flange accepts standard motor spigots, while the B5 output flange mates to gear units or pulleys without alignment adapters.
