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...

The QR145, QR200 and QR12 series of optical encoders have 28 AWG conductors in the standard flying lead cable. This gauge of cable is excellent for tight bends and fitting in applications where space is a premium. The conductors can easily handle the 250 mA max current requirement of the...

I received a phone call the other day that caught me a bit off guard. A customer was asking what tolerance they need to have on their motor shaft for it to fit with one of our incremental encoders. I reflexively told the customer that we machine our shaft...

When using an incremental rotary encoder, you often have to know how many pulses there are per degree of rotation. This is a very straightforward math problem. Pulses per Degree = Number of encoder pulses per rotation/Number of degrees in a circle For a 5,000 line count incremental encoder we...

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...

Quantum Devices is now offering an interface cable to our QDH20 series of industrial incremental encoders. While we like to focus more on building encoders than “add on” products, we did find this to be something that made sense to offer with our QDH20 encoders. At this time, the ten...

I recently received an e-mail asking for some help picking the right resolution for an optical incremental encoder. I have removed the personal information and the drive/controller information, otherwise the e-mail is verbatim: Hi, I am using a motor controller in dual loop velocity mode. What resolution incremental encoder would...
