Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

Optical rotary encoders are the most widely used way to transform mechanical rotary motion into electrical signals. There are three basic configurations for optical encoders: incremental, absolute, ...

AEDR-871x is part of Avago Technologies’ new series of Reflective Optical Encoders designed for Low Power Miniaturized Motion Control Systems. The device is a 3-Channel High Resolution Reflective ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

While standard optical encoders have traditionally been used to meet the needs of high-precision sensing and control applications (such as steering-wheel position detection or industrial motion ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.

Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...

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 ...

Purdue University alumnus Sergey Zakharov, co-founder and chief technology officer of ZS Instruments, holds an optical encoder wafer created by a prototype of the company’s novel technology. ZS ...
