Magnetic particle brakes are maintenance free and ideal for clean room operation or use in any production area where traditional brake dust emissions are not permitted. Also called powder brakes, these units provide smooth and repeatable torque output proportional to electric input current. DFE has partnered with Placid Industries to deliver high quality magnetic particle 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. For assistance sizing a magnetic particle brake or a complete tension control system, e-mail an applications engineer today or complete the ‘Request Info’ form. Placid Industries’ brakes and clutches are manufactured to exacting standards in the USA and come with a one year warranty. Most models are available to ship in 1-2 days.
