M-238 High-Load Linear Actuator

Dynamic, High-Resolution Precision Drive with DC Motor and Direct Position Measuring

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

M-238.5PG

M-238, dimensions in mm

The repeatability of the M-238.5PL with linear encoder is less than 0.3 µm.

The M-238 requires less than 1.5 seconds for a 30-mm step.

The velocity constancy of an M-238.5PL at 30 mm/s.

High-resolution, high-load linear actuator. Highly dynamic, closed-loop DC motors for high velocities.

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

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.

Precision alignment, external drive element for guided systems.
