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, ...

My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.

At NAB, Link Research announced low bit-rate upgrades to its L1000 decoder, extending the standard minimum bit rate of 2.5 Mb/s down to 500 kb/s. Until now the L1000 was only suited to high bit-rate ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...
