High-Load Linear Actuator Dynamic, High-Resolution Precision Drive with DC Motor and Direct Position Measuring M-238  Optional: Linear encoder for direct position measuring  High load capacity to 400 N  Travel range 50 mm  Resolution to 0.1 µm  Velocity to 30 mm/s Reference-class linear drive High-resolution, high-load linear actuator. Highly dynamic, closed-loop DC motors for high velocities. High-quality components Recirculating ball screw provides high velocity and long lifetime. Low-friction output shaft bearing can handle lateral forces to 100N. Nonrotating end piece for uniform motion prevents wobble, torque, and wear at the point of contact. Includes flat and spherical end piece for decoupling of lateral and tilt forces. Noncontact limit switches protect the mechanical system. A direction-sensing reference switch supports automation applications Highly accurate position measuring with incremental linear encoder Noncontact optical encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement. Application fields Precision alignment, external drive element for guided systems.
