Product Description:
The 05.P1.300-0807 is a normally closed electromagnetic safety brake produced by KEB as part of the P1 Encoders and Brakes series. The device is intended for direct integration with fractional-kilowatt servo motors, where it provides static holding torque and emergency stopping capability without requiring a mechanical clutch. When the brake is de-energized, its internal spring pack presses the friction plates together and locks the shaft. Energizing the coil retracts the armature and releases the shaft so that controlled motion can resume. This operating method helps secure vertical axes and rotary positioning tables in industrial automation systems.
The brake delivers a continuous holding torque of 6.1 Nm while consuming 12 W of coil power at the rated voltage. Its 100% duty cycle allows the coil to remain energized continuously, enabling the brake to stay released during long production runs without overheating. In dynamic applications, the rotor can operate at speeds up to 10,000 rpm while keeping centrifugal forces within the limits of the friction liner. Engagement with a DC supply is completed within 20 ms or less, which helps minimize shaft movement after a stop signal. A magnetic air gap between 0.2 mm and 0.5 mm supports consistent armature movement as the brake temperature changes.
During emergency deceleration, the braking surface can tolerate speeds up to 6,000 rpm, provided that the resulting thermal energy is allowed to dissipate. When voltage is removed, the brake fully engages within 50 ms or less, allowing the spring force to restrain the connected load promptly. The housing has an IP40 protection rating, making it suitable for installation in a vented enclosure where exposure to airborne particles is limited. Its electrical insulation meets Overvoltage Category III requirements, providing suitable clearance and creepage distances for standard industrial control circuits. The response delay is no more than 25 ms with an AC supply and no more than 3 ms with a DC supply. At a brake temperature of 120 °C, the unit maintains 4 Nm of static torque for holding loads under elevated thermal conditions.
