Hysteresis Brakes

Operating range from 0.04 oz-inches to 250 oz-inches of torque.

Hysteresis brakes are maintenance free and ideal for clean room operation or use in any production area where traditional brake dust emissions are not permitted. These units provide smooth and repeatable torque output proportional to electric input current.

DFE has partnered with Placid Industries to deliver high quality hysteresis brakes perfect for use with our closed-loop tension controllers and load cells. In our experience, Placid Industries' brakes deliver some of the widest torque ranges available with ultra smooth engagement. These important characteristics make Placid Industries' brakes ideal for use in high-performance tension control systems.
