Digital Linear Actuator (External Nut)
Conversion of rotary to linear motion inside a linear actuator is accomplished through a threaded
nut and lead screw. The external shaft is threaded. In order to generate linear motion the lead screw
must rotating together with rotor, and the shaft threads engages the nut resulting in linear motion.
Changing the direction of rotation combination determines the linear travel per step of the nut. The
travel length and speed can be digital controlled by the input of data pulses. Moons DLA 16HY0416-
02N, is designed as travel of 0.004mm per step and can be accurately controlled to drive 40mm
movement by a 10K data pulses input. Application: Various zoom controls, X-Y stages, as well as
other linear motion control applications.
