Disc brake COMBISTOP 38D

frictionmechanicalspring

Description
The 38D double brake doubles the safety level and covers a range that is prepared for tasks with redundant brake circuits. The mechanical design with two safety spring-applied brakes, which are completely independent of each other, meets the requirements according to DIN 56950 (BGV C1). The redundant brake system is delivered ready for use and adjusted by KEB.

Highlights

• Ten sizes
• Two redundant brake circuits
• Ready to install, adjusted air gap
• Used as a service brake or holding brake
• Up to ISO class H in accordance with VDE 0580
• cCSAus-certified
• Protection class up to IP67
• Designed for S1 operation or 100 % duty cycle
• Up to seven million switching cycles as standard
• Standard voltages 24 / 105 / 180 / 205V

Options (summary)

• Manual release — optional hand release for manual opening of the brake (useful in de-energised situations or if rotor is worn).
• Microswitch — optional microswitch to monitor performance or wear (recommended for brake motors on hoisting gear and load lifting systems, esp. when used with frequency inverters).
• Flange / friction disc — optional flange or, for smaller sizes, friction disc to provide an optimal counter-friction surface when motor endshield lacks required properties.
• Dust protection ring — optional ring to increase IP protection for dusty/damp environments and protection against accidental contact (can achieve IP54 under the motor hood and up to IP44 at the open end).
• Shaft sealing ring / sealing plug — for sealing continuous shaft against external environment; sealing plug available where no shaft is present.
• CCV version — design for harsh and cold environments, suitable down to -40 °C.
• Encoder attachment / rear-side threaded holes — optional rear-side threaded holes and bore pattern for attaching rotary encoder, fan or sensor.
• Braking torque — braking torque can be increased or reduced according to customer specifications during production.
• Flat design — reduced housing / overall length available for applications with installation depth constraints (delivered ready for use, adjusted by KEB).
• Customized voltages — custom coil voltages available on request.
• Connector assembly — ready-to-connect cables with plugs, contacts or wire end ferrules available to simplify assembly.
• Certificates — factory certificate 2.1 (DIN EN 10204) and acceptance test certificate 3.1 (DIN EN 10204) available on request (certificate 3.1 includes results of specific tests, e.g. torque test).
