Optical Encoder Incremental Signal Measurement

March 26, 2014

While most of us are familiar with how to measure something in mechanical degrees, incremental encoder signals are measured in electrical degrees. 360 electrical degrees is the period in which a signal completes one high to low transition. This can be in any sort of waveform, but for encoders electrical...

Interfacing to 26C31 Line Drivers in QDI Rotary Encoders

March 2, 2013

Encoder Electrical Structure The internal electrical structure of the QDI series of encoders consists of a photo interrupted light source that is picked up by a common mode photo detector array. “Common mode” means that there are two channels that are at exact opposite states in any position. The advantage...
