BFK458 Intorq Spring Applied Electomagnetic 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 application▪ Brake 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 transmission▪ Designed for dry runningA powerful and complete range▪ 9 sizes▪ Standard voltages [V DC] 24, 96, 103, 170,180, 190, 205▪ Graduated torque range from 1.5 - 600 Nm▪ Enclosure according to IP00 ...
