Micro Servo Actuators MSA

With nominal loads up to 100N, feed rates up to 80mm/s, strokes up to 56mm, controlling and absolute encoder (potentiometer) integrated into the housing, smaller than a cigarette box Micro servo actuators achieve amazing performance. A servomotor with integrated micro controller drives a spur gear box and thus a tiny trapezoidal screw. The screw is made of metal in size TR3 or TR4. The parameter setting of the Micro Servo Actuator is possible over an RS485 interface, an USB interface board and intuitive PC software.
