What is meant by Rotary Incremental Encoder Index Pulse “Gating”?

May 7, 2020

An INDEX PULSE is a digital signal that is generated from an incremental encoder on an individual output channel, once per revolution. This unique pulse may be used for several purposes: In conjunction with a counter, it can be used to track the total number of shaft rotations. It may...

Quantum Devices Celebrates 30 Years of US Made Incremental Encoders

April 9, 2020

Featured in Cision | PR Web

For OEMs whose equipment uses incremental optical encoders to manage AC/DC motors, working with a supplier with leading edge technology and US only based production has proven to be a winning strategy. Consistent product innovations over the past 30 years have allowed these OEMs...

Very High-Resolution Application Solutions with QR12 and LP12 Sine/Cosine Incremental Encoder Output

February 14, 2020

For applications that require extremely high resolution, OEM equipment designers have historically chosen to incorporate absolute encoders into their designs. Quantum Devices’ QR12 and LP12 sine/cosine encoders are now challenging the perception that absolute encoders are the only high-resolution solution available to the industry. The benefits of QR12 or LP12...

Incremental Rotary Encoders for Automated Guided Vehicle (AGV) Control

January 15, 2020

Warehouse automation systems have progressed dramatically over the last decade thanks to improvements in software, actuation, sensing, communication and control technology. AGVs have benefited greatly from these advances, and as a result are being applied to a broadening range of applications. AGVs have defined paths or areas within which they...

August 29, 2019

Quantum Devices recently released a technical comparison of our QM35 and QML35 modular optical encoders: Download Printer-Friendly Version How the QM35 and QML35 Stack up Against the Competition Quantum Devices QM35 and QML35 optical encoders are high performance, low profile bearingless encoders ideal for high volume OEM applications and priced...

Miniature Rotary Encoder Boasts High Resolution and Built-In Brushless DC Motor Commutation

July 29, 2019

Featured in CISION/PRWeb Quantum Devices, Inc. is announcing a new step forward in miniaturization of commutating/incremental, optical encoder technology. The new QM22 series of incremental encoders offers a super compact 22mm diameter and a 12.4 mm thickness. Ideal for high volume OEM applications and fits on a NEMA 11 BLDC...

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...

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...

Incremental Encoder Lathe Automation

March 29, 2016

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...
