BFK458 Type Intorq Electromagnetic BrakeINTORQ BFK458 spring-applied brakeTorque range: 1.5 – 600 NmElectromagnetically released spring-applied brakes are used wherever masses in motion have to be decelerated as quickly as possible or where masses must be held in a defined position. The braking force is applied by tappet springs. Thus the braking torque generated by friction locking remains available in the deenergised status – even in the event of mains failure. The brake is released electromagnetically. Fields of applicationBrake motors, Conveyors, Cranes, Storage technology, Industrial trucks, Wood working machines, Stage machinery, Vehicles for the disabled, Automation technology, Controlled drives, Gate drives, Escalators. INTORQ Brake Model / Type BFK 458.06 E, BFK 458.08 E, BFK 458.10 E, BFK 458.12 E, BFK 458.14 E, BFK 458.16 E, BFK 458.18 E, BFK 458.20 E, BFK 458.25 ETorque transmissionDesigned for dry runningA powerful and complete range9 sizesStandard voltages [V DC] 24, 96, 103, 170,180, 190, 205Graduated torque range from 1.5 - 600 NmEnclosure according to IP00 ...
