Linear actuator LSMA-167
LSMA miniature linear actuators designed for the space confined applications while retaining the high reliability required in production environments. It is an ideal choice for measurement, testing, alignment and component assembly in any application on the factory floor or laboratory environments.
The precision ball screw or micrometer grade lead screw provide excellent accuracy and repeatability with ultra-fine positioning resolution capability of 0.1 micron when driven by the stepper motor. The servomotor version is equipped with a rotary encoder and provides exceptionally smooth travel.

Open loop Micro-stepping resolution = screw_lead/200/microsteps_per_step
where:
motor has 200 full steps/rev
driver micro-stepping resolution 64, 128, 256 micro-steps/step
Closed loop servo resolution = screw_lead/encoder_cpr/4
where:
encoder_cpr is number of encoder counts per revolution
4 is post-quad processing in the motion controller
