A hollow shaft encoder is a type of rotary encoder characterized by a central void or hole in the rotating shaft.
The operating principle of hollow shaft encoders typically employs two main methods: optical and magnetic. Optical encoders utilize optical sensors and a disk to detect changes in rotation angle, while magnetic encoders employ magnetic sensors and a disk for the same purpose.
Hollow shaft encoders find widespread use in industrial machinery for precisely measuring the position and speed of rotating shafts. They play crucial roles in machine tools and robotics for precise control, in packaging and printing machinery for functions like film and paper feeding control, and in automotive systems for controlling features such as power steering and brakes. Key features of hollow shaft encoders include their space-saving design along the shaft axis, ease of installation, high precision, durability, and compatibility with various output formats.
