Low profile motorized actuators with precision ball screw provide exceptional accuracy, repeatability and ultra-fine positioning resolution capability to 1 micron in a very compact, low profile unit. They are ideal for space-critical applications such as optical, laser applications and vacuum operation.

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
