Electric / Electromagnetic Jaw Brakes

Electric Jaw Electromagnetic Brake

Jaw Brakes are designed to optimize size and space in your application. These electromagnetic brakes are ideally suited for positioning, holding and indexing, as well as situations that require the unit to maintaining positive registration between input and output shaft.

With pins available for single-position engagement, electric jaw brakes are often used in applications that require exact positioning, including imaging, robotics, printing and labeling.

As with all standard CJM products, our electromagnetic brakes can be modified for special uses. We can custom design a solution for your application.

Features of Jaw Electromagnetic Brakes

Electric Jaw Brakes are available with either 24 or 100 volt DC coils as standard equipment, though other voltages are available to meet your needs. Carlyle Johnson stocks coils with voltages ranging 6 to 240 volts DC.

CJM jaw electromagnetic brakes feature bi-directional operation, meaning operation is not dependent on rotation. Pins are also available with these designs to permit single position engagement.
