MXEA Electric Caliper Brakes


The EA actuator is a spring applied, electrically released unit designed for use with the Twiflex MX range of disc brake calipers. A 175W pancake motor drives a ball screw mechanism, retracting the brake.

A feature of the unit is a patented self-adjusting mechanism which maintains a constant air gap (and consequently braking force) between pad and disc as the pads wear.

The assembly is contained in a rugged, cast aluminium housing, designed for service in the harshest environments, which mounts directly to one arm of the MX caliper.

The MXEA is supplied complete with a solid state controller, suitable for all AC supply voltages, which converts the supply to the required DC output for the pancake motor. A 24VDC unit is also available. The brake is released when power to the controller is switched on, and applied when power is disconnected. Controlled application of the brake occurs, electrically damped by using the motor back E.M.F. and a damping resistor.

The controller is housed in a strong, steel, wall mounted enclosure (215mm x 215mm x 150mm deep), protected to IP44 as standard (higher rating on request).

Braking force adjustable to 50% of maximum.
