RUKO KEB-HM-63,0mm freno elettromagnetico a molla, 4 Nm, 24 V DC

Unexpected motion or drift in a stopped machine can damage tooling, scrap parts, or injure an operator. The RUKO KEB-HM-63,0mm is a spring-applied electromagnetic brake that holds the shaft securely whenever power is removed, and releases only when 24 V DC is applied. It serves as a holding brake or emergency stop brake on motors, gearboxes, and linear axes.

Who is it for

Machine builders, retrofitters, and maintenance teams who need a compact, flange-mounted brake for small to medium servo or stepper drives. It suits packaging machines, robotics, conveyors, and automated assembly stations where a power-off holding function is required.

Main features

• Spring-applied, electrically released: braking force is generated by springs, so the brake engages automatically on power loss or emergency stop.
• Rated torque 4 Nm at a nominal diameter of 63 mm, suitable for many small drives.
• 24 V DC coil with 12 W rated power, compatible with common industrial control voltages.
• Flange mounting for direct attachment to motor or gearbox housings.
• Flying leads for simple electrical connection.
• IP54 protection against dust and splashing water.
• Insulation class F (155 °C) and operating temperature range -20 to +40 °C.

Tips

Check the air gap after installation and periodically during service; if it exceeds the wear reserve, the brake may need adjustment or replacement. Ensure the 24 V DC supply is stable and within tolerance to guarantee reliable release. For emergency stop applications, verify compliance with relevant safety standards for the complete system.
