Geared rotary actuators

The MR geared rotary actuator range consists of three models of DC geared motors with integrated encoder or potentiometer, combined with worm gearboxes. With IP65 enclosure, a maintenance free design and IEC output dimensions, it suits a wide scope positioning applications. The first two models in the MR range have output torques of 3 and 15Nm respectively. DC motors at either 12 or 24V provide output speeds from 60 to 500r/min depending on the model and the ratio of the worm gearbox. A two channel encoder gives positioning or speed feedback at either 1 or 4 pulses per revolution. Depending on the gear ratio, this corresponds to between 12 and 276 pulses per revolution of the output shaft. The third model has a rated torque of 15Nm, but instead of the encoder it has two built-in stroke limit switches that can be set in a range from 20 to 140 revolutions of the output shaft and there is a 5kOhm rotary potentiometer for position feedback.
