Incremental Encoder Line Card

September 19, 2018

Quantum Devices offers a full range of transmissive incremental encoders. Our rotary encoders are used in industrial and commercial motion control, including medical equipment, industrial automation, and automated guided vehicles (AGV). Our full incremental encoder line card is now available online. This is a helpful resource for comparing the configuration options available...

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...

Cable Length Considerations with Incremental Encoders

March 16, 2016

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...

QD145 Incremental Encoder IP66 Sealing Option

February 24, 2016

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...

Cross-Referencing RENCO Incremental Encoders for Replacement

February 3, 2016

We have always been able to come up with a suitable replacement for Renco encoders, but our customers are making us aware that we need to point that out. For those who don’t know, Renco, after being absorbed by Heidenhain, made the decision to eliminate much of their encoder product...
