Through-Axis Encoders

Product Description

A Through-Axis Encoder is a high-precision rotary encoder designed with a Hollow Shaft structure that allows the encoder to be mounted directly onto a rotating shaft.Unlike traditional solid shaft encoders,the through-axis design enables the machine shaft to pass through the center of the encoder,eliminating the need for additional couplings or adapters.

Also known as a hollow shaft encoder or through-bore encoder,this type of encoder provides accurate feedback of position,speed,and rotation direction while offering a compact and space-saving installation solution.Its simplified mechanical structure makes it ideal for industrial automation,servo systems,robotics,CNC equipment,and other precision motion control applications.

Our through-axis encoders are engineered with high-quality components,stable signal output,and excellent mechanical durability.They support various resolutions,output signals,shaft sizes,and mounting configurations to meet different OEM and industrial requirements.
