Unlike electric actuators with only two positions, these actuators have a carriage that slides to any point, similar to the head on an inkjet printer. An integrated motor and precision ball screw move the carriage, and a built-in encoder sends data to the controller to make sure the carriage is in the right place. The accurate, repeatable motion works well for automated processes like assembly and inspection.

Setup is simple—connect the controller to the actuator and your computer using the included cables. Program the carriage’s position, speed, and acceleration with the free downloadable software, THK D-STEP. Use your PLC to run the program. To add limits or start other processes as the carriage moves, the controller can also read data from NPN sensors (not included).

These low-maintenance actuators are enclosed, so debris can’t get in and cause damage. Lubrication is sealed inside, so you don’t need to add more.

Travel distance per turn, also known as screw lead, is how far the carriage moves with one turn of the motor.
