The EA series has a 7 inch color LCD screen which provide inactive graphic display and step by step operation graphical guidance for all DRO functions, which makes EA-926 extremely user friendly, allow operators can implement all the powerful DRO function within few minutes after switch on the DRO.
Purpose: It is matched with various sensors for measuring on machine tools and displaying the measured results in digital form.
Optical Linear Encoder
This type of encoder shines light onto a slit pattern that moves along a linear axis, and a sensor detects the light that passes through (or is reflected by) the pattern and outputs it as position information.
linear encoder
Optical Rotary Encoder
This type of encoder shines light onto a rotating slit pattern, detects the light passing through (or reflecting off) the sensor, and outputs it as position information.
