What is a Transmissive Rotary Encoder?

July 1, 2019

A transmissive rotary encoder, also known as a shaft encoder, is an optical, electromechanical device that is used to measure and control rotational motion in a very broad range of industries and applications. Internal sensors detect interruptions in a light source and send corresponding analog or digital signals to system...

Expanded Bore Options for HR12 Optical Encoder

January 3, 2019

As outlined in a previous post, our HR12 optical encoder is a popular choice for HEDS replacement. We also have found that the HR12 serves as a great HEDM replacement. Our HR12 rotary encoder boasts a wide range of line count options from 24 to 20,000 PPR as well as many...

Troubleshooting Encoder RPM Calculation using Oscilloscope

April 24, 2016

I received this e-mail from a potential customer who is trying to determine why he had a skewed encoder waveform. His name has been changed to protect his identity. Hi Jim, I have just come across your page on RPM calculation using an optical encoder and oscilloscope. I was keen...

Air Gap in High Resolution Optical Encoders

April 18, 2016

As the resolution of optical encoders increases, the distance from sensor to disk decreases. In the incremental encoder industry, this distance is called the “Air Gap”. In the side view photo of an optical encoder above, the two red lines indicate the air gap between the sensor and disk in...
