Teardown: Inside an industrial absolute encoder

April 26, 2022 By Lee Teschler

If you go to the Wikipedia page on absolute encoders, you’ll find descriptions of these devices mentioning multiple code rings, glass or plastic discs, and configurations of sliding contacts arranged so each contact wipes against a metal disc at a different distance from a turning shaft. Actually, you’d be hard pressed to find any of […]

What is the difference between a thermal IR sensor and a quantum IR sensor?

March 9, 2021 By Randy Frank

Infrared radiation (IR) can be detected by thermal IR and quantum IR sensors. A thermal IR sensor uses infrared energy as heat for detection and its sensitivity is independent of wavelengths. Therefore, it can detect objects in the near IR, mid IR, and far IR bands. The non-contact detectors do not require cooling after exposure […]
