Low Voltage Rotary Actuators LTS Series

Low voltage rotary actuators can be divided into two models depending on the different application : I series and T series ,all product contains dual encoders, drives, and brakes.Low-voltage series has an exquisite design and compact structure. The compact size contains major components such as servo drive, motor-end absolute encoder, output-end absolute encoder, frameless torque motor, brake, and precision harmonic reducer. Save customers the labor and time costs of selecting, designing, purchasing, and assembling hundreds of mechanical and electronic devices.

Advantage

High torque, small size
High product accuracy, absolute positioning accuracy is controlled within 20 arc seconds
Large hollow hole, convenient for wiring, piping, laser, etc
Strong environmental adaptability, IP65 protection level
Maintenance-free, no need to replace grease during the entire life cycle
Long life, accuracy remains unchanged after more than 15,000 hours of usage
