Product Description:

The 06.P1.100-0847 is an electromagnetic brake supplied by KEB in the P1 Encoders and Brakes series. It is intended to couple directly to servo or stepper motor shafts and provide fail-safe holding whenever the control system removes power. By converting electrical energy into magnetic attraction, the brake clamps its friction disc against the hub so vertical axes, rotary indexers, or conveyor sections stay in position during power loss, maintenance, or emergency stops. A slim housing and standard flange pattern let machine builders install the unit inside limited axial spaces without additional adapter plates.

This brake is engineered for continuous operation at a 100% duty cycle, so thermal cycling does not interrupt repetitive production tasks. A circular mounting face with a 80 mm diameter matches common IEC motor endbells, while the round flange style simplifies alignment during assembly. Air-gap tolerances influence torque, so the rotor-to-stator clearance must never exceed the 0.65 mm maximum limit to maintain magnetic flux density. The friction materials withstand ambient and coil temperatures up to 120°C without glazing, ensuring reliable engagement under prolonged heating. When supplied within its temperature window, the brake delivers a rated holding capacity of 12 Nm, enough to secure medium-inertia loads. An IP20 protection class indicates that the unit needs installation inside a guarded enclosure free from dripping liquids or conductive dust.

The nominal factory-set clearance is held to 0.3 mm, giving short pull-in times and minimizing coil current during engagement. Operation continues in cold storage areas because components remain flexible down to -40°C. Electrical demand is modest: the coil draws only 18 W when energized, keeping panel heat low and allowing multiple brakes to share compact power supplies. Control circuits typically feed the device with a 24 VDC source, enabling direct connection to common PLC output relays without additional converters.
