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...

I received this e-mail from a potential customer who is trying to determine why his Encoder waveform doesn’t look right. His name has been changed to protect his identity. Hi Jim I have just come across your Web page on RPM calculation using an optical encoder and oscilloscope. I was...

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...

I was featured in an interview with EEweb. Jim Miller – Application and Design Engineer at Quantum Devices How did you get into electronics/ engineering and when did you start? I started when I was pretty young, like nine or ten, taking apart radios and using an old wood-burning tool...

I have been working on a project to automate a manual lathing operation for our incremental encoder/optical encoder line. To keep things simple, thumb switches allow the set point, along with some offsets for fine-tuning, to be entered. I am not completely finished with project, but in the video below...
