New Products released | Enter optocoupler packaging market to boost the development of industrial intelligence.

Mar 11, 2022

"Optocoupler" is abbreviated as OC , which is a (electrical-optical-electrical) conversion device that transmits electrical signals by the light as a medium. By assembling the light-source and the light-receiver in a same closed casing and isolating each other with an insulator, the non-contact signal conversion and transmission between these two control units is realized.

Refond Optoelectronics (hereinafter called Refond) takes LED light-source packaging as its main business. After 22 years of hard work , Refond can produce the entire LED light source products . Base on this , Refond brand is widely recognized at home and abroad. With more and more cooperation with customers and the accumulation and progress on technology , nowadays Refond business not only covers LED light source devices, but also the light display technology (Mini LED) and the application solutions for light sensor device , which will be the main development direction in the next few years.

As a transmission medium, the optocoupler enables the electrical signal to have one-way transmission capability. The input and output end are isolated electrically and completely , which the output signal won’t interfere with the input end. It owns many advantages such as the strong anti-interference ability, a stable performance, no contact, a long service life and the high transmission efficiency ect. Based on these advantages, optocouplers have been widely used at various levels in the industrial area.
