Product Description

Hollow shaft rotary actuators

                                                                                           KAH series hollow shaft rotary actuators
Main features

1.KAT series hollow shaft rotary actuators with enlarging aperture provide large-torque and highprecision rotary actuation. With integrated design, processing and assembly technique, it is provided with high precision speed reducer, frameless torque motor, multi-turn hollow shaft absolute encoder, brake and intelligent sensor.
2.Compared with KAH series, KAT series are provided with internal through hole with enlarging aperture. An internal through hole is set to facilitate threading wires, gas pipe and laser beams and simplify system structure.
3.The positioning precision of rotary actuator is within 30 Arc sec.
4.An internal through hole is set to facilitate threading wires, gas pipe and laser beams and simplify system structure.
5.Dozens of product models are provided to meet diversified needs, and the products with 220 VAC, 110 VAC and 48 VAC voltages are available.
6.The high protection grade (IP67) makes the product applicable to severe working environment.
8.It can be used by matching with KDE series EtherCAT bus servo drives to realize ultra-low vibration controland reliable and stable operation. It provides an integrated drive control solution.
