This simple circuit provides better than 1% accuracy in optically coupling a DC voltage signal. To compensate for the non-linearity of the optical isolator, an identical device is connected in the ...

An optical isolator developed at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) could drastically improve optical systems for many practical applications. All optical ...

Alan Martin, Engineer Extraordinaire, once told me, “You never regret adding isolation between your circuits.” While he was speaking in the context of power supplies, the same goes for isolating ...

Optical isolation and nonreciprocal devices are pivotal components in modern photonic systems, ensuring unidirectional light propagation and safeguarding sensitive equipment from unwanted reflections.

High-speed optical isolators solve interface problems between an incremental encoder signal and a PLC, servodrive, or other input devices. Designed for use with single-ended or differential ...

Researchers from the University of Illinois at Urbana-Champaign have demonstrated a new level of optical isolation necessary to advance on-chip optical signal processing. The technique involving light ...

Having problems with your process controls and electrical instrumentation? The source may be a grounding disturbance known as a ground loop. According to the ANSI/ IEEE Standard Dictionary of ...

Static common-mode specifications have been the traditional standard used to measure isolators and compare devices with different construction or technologies. However, that standard is no longer an ...

Tiny circuits can go the distance. Researchers have mapped a noise-reducing magneto-optical response that occurs in fiber-optic communications, opening the door for new materials technologies. Optical ...

The OPI1270, OPI1280, and OPI1290 Series of optical encoders feature a visible red LED, sit in heavy-duty opaque molded plastic housings that shield the optical signal from dust, and are coupled by a ...
