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 or magnetic linear encoders are traditionally used to provide position feedback in applications with frequent product changes or and sophisticated machining. Linear encoders improve the ...

In aviation the term fly-by-wire means that the control surfaces of an aircraft are operated by actuators rather than via cables and rods, with electrical signals transmitting information from the ...

The AEDR 8400 series are the industry’s smallest reflective incremental optical encoders, according to Avago Technologies. The encoders combine this extremely small size—3.00 mm by 3.28 mm by 1.262 mm ...

NUMERIK JENA’s LIK 2 optical linear encoder series is now ready for high and ultra high vacuum applications where motion feedback is required inside the vacuum chamber. This small non-contact encoder ...

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 ...

Renishaw (www.renishaw.com) has developed new linear encoders that feature a special stainless steel scale, ultralow ±30 nm cyclic error, patented filtering optics and ±4μm accuracy to deliver the ...

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 ...
