Johnson Electric Rotary Solenoid, 30.2 mm Diameter, 25%, 40W, 27.8 V dc

Johnson Electric’s BTA actuator platform offers high speed controllability in rotary stroke applications. The BTA has a single phase coil with three stator poles and matching rotor pole. When the coil is energized, the poles align along the flux path. The three pole design allows a stroke of up to 45°. Since BTA technology does not require full stroke actuation, stops can be used to attain maximum life as well as optimum stroke / torque capacity. Using simple pulse width modulation to control coil current, the BTA allows open or closed loop velocity and maximum position control.
