The Coupler Motor Brake is designed for indexing applications where cycle rates are too low to justify a clutch/brake (roughly less than 10 CPM) or in applications where the motor must reverse. The Coupler Brake utilizes a standard Nema C-Face motor driving through a durable, keyless collet connection. Common applications include palletizers, indexing conveyors, shrink wrappers package and general material handling equipment. The Coupler Brakes are rated from 6 Ft. Lbs. to 450 Ft.
