HEIDENHAIN’s family of KGM grid encoders have once again been improved to better meet the needs of CNC-controlled machine users who require accuracy testing. HEIDENHAIN’s family of KGM grid encoders ...

Is it really possible to build a rotary encoder out of a flattened tin can and a couple of photodetectors? Sure it’s possible, but what kind of resolution are you going to get from such a contraption?

A typical linear encoder consists of a scanning unit and a scale. The scale is generally glass and is cemented to a support, usually an aluminum extrusion. The scanning unit contains a light source, ...
