FAQ

Q1: How does an absolute encoder work?❯

An absolute encoder uses a coded disk or magnetic sensing system that assigns a unique digital value to each shaft position. As the shaft rotates, the sensor reads this code and outputs the exact position instantly, even after power loss or restart.

Q2: How to install an absolute encoder?❯

To install an absolute encoder, mount it securely to the rotating shaft using a suitable coupling or hollow shaft, ensure proper alignment to avoid shaft stress, and fix the encoder housing to prevent rotation. Then connect the power supply and signal or communication cables according to the encoder interface, and perform initial configuration or zero setting if required.

Q3: What is the purpose of a rotary encoder?❯

A rotary encoder is used to measure the angular position, rotation direction, and rotational speed of a shaft. It provides precise feedback for motion control and positioning in motors, automation equipment, robotics, CNC machines, and industrial control systems.
