Photoelectric Shaft Encoders

Based on photoelectric converting principle the photoelectric shaft encoders transfer the mechanical moving variables - geometrical displacement data of revolving shaft to the digital electrical pulse signals, then the electrical signals are processed in a computer and the computer uses the processed data to realize the automatic control of the machines.

Features:
low cost, small size, light weight, digital encoding, high contrast, high output.

Applications:
measurement of space position, measurement of linear displacement, measurement of angle displacement, automatic control.

Specifications:

(1) Incremental Angle Encoders
