Optical encoders

A line of compact optical encoder systems for use in a variety of closed-loop motion control systems have sensors that enhance the first orders of diffraction to create a pure signal via a laser light source. A variety of rotary and linear gratings are available with a choice of three electronic modules, allowing interpolation out to 14 bits with 2.5-µm to <1-nm resolution.
