Details

Designed for compact motion modules, the K9030 combines an integrated drive and encoder for precise servo control.

An integrated electric drive layout keeps wiring simple while supporting high-torque output in a lightweight, flat form factor.

Clear interface labeling helps speed up installation for RS485/CAN communication, power input, and UART signal connections.
