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. Now the KGM 281 grid encoder is available ...

Encoders are critical to the production of advanced electronics, one of the fastest growing and advancing industries in the world. Rotary, angle and linear encoders are all used in one form or another ...

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?

Optical encoders are nothing new; they can be found in everything from mice to printers. They’re great for allowing DC motors to know their exact position and even current direction. If this is ...

Why are there so many different angle encoders on the market? Why do they use different scanning and measuring methods? And which one should a designer choose? To answer those questions, engineers at ...

NUM, the CNC automation group, introduced two series of brushless servomotor that it claimed will save on machine tool installation costs by eliminating the need for a separate encoder cable. Machine ...
