Incremental Hollow Encoder

The Incremental Hollow Encoder is a high-performance rotary position sensor designed for accurate measurement of displacement,speed,and direction in modern motion control systems.As a specialized incremental hollow shaft encoder,it converts mechanical rotation into electrical pulse signals through optical or magnetic coding technology,enabling precise real-time feedback for automation and industrial equipment.

With its through-shaft structure,the encoder allows direct installation on motor shafts or rotating spindles,making it a compact and efficient hollow rotary encoder solution for space-constrained and high-precision applications.

Product Description

The working principle of the Incremental Hollow Encoder is based on a coded disc divided into evenly spaced light and dark segments.As the shaft rotates,the optical or magnetic sensor detects changes in signals and outputs A,B,and Z phase pulses.These pulses are then counted by a controller to determine position,speed,and direction.

This makes it a reliable incremental hollow encoder switch system widely used in motion feedback applications where relative position tracking is required rather than absolute position memory.

Unlike absolute encoders,the system resets after power loss and requires homing,but it offers excellent cost efficiency and high resolution,making it ideal for industrial automation.
