GBM Three channels Optical Kit Encoder
Product Features
Optical Kit Encoders can be equipped at the end of servo motors, DC motors and stepping motors.
Optical Kit Encoders are high precision digital sensors testing the speed, angle and location. Light from LED goes through grating coding dish which is tightly installed on the motor shaft, the receptor(phototube) turns the change of brightness alternation into pulse and amplify and handle it in the controller. Because of the influence of gear backlash or driving belt error, DC motors and stepping motors use optical kit encoders which are less than 500 lines.
Optical Kit Encoders can be divided into two categories: two channels and three channels. As incremental encoder, Three channels encoder can directly output three sets of square wave pulse(A 、 B and Z phase)by adopting Photoelectric Conversion Principle.
