Incremental rotary encoder resolution equals the number of measuring units in one revolution of the shaft, and is measured in PPR (pulses per revolution). Because incremental rotary encoders have A/B outputs, resolution is 4 times the PPR: accounting for 2 edges each on the A channel and B channel. High-resolution...

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...

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...

Quantum Devices Inc. has a mounting option that allows for IP66 sealing of the QR145 Incremental Encoder. There are two o-rings in the clam shell design; one o-ring seals the encoder to the mounting surface (usually a motor) and the other o-ring seals the end bell housing that covers the...

Potentiometer vs Encoder Recently, I decided to catalog the competitive incremental encoders that have populated the shelves surrounding my desk. In doing so, I was surprised to find that many of our competitors use potentiometers in their designs. I can understand why they need to use potentiometers. In most...

Seeing Encoder Quadrature with a Two-Channel Scope I received an e-mail from a customer concerned about the “out of control” optical encoder signals he was seeing on his Oscilloscope. The photo below shows the type of signal he was seeing: The encoder in question was a 10,000 Line Count optical...
