TT electronics OPTEK Technology has designed an OPI1268S optoisolator with GaAlAs LED, which can be used in harsh environments and explosion-proof applications.

The UL- and VDE-rated optical isolator with 20KV isolation and 2Mbit/s data transmission rates designed to comply with ATEX and ICEex certifications for electrical equipment used in hazardous areas, as well as IP65 standards for environmental sealing. 

According to Rodney Bailey, VP optoelectronic component solutions for TT electronics OPTEK Technology, the OPI1268S optoisolator is the only high voltage device on the market with this comprehensive range of certifications  “Designed to carry a UL, VDE rating, ATEX/IECex certifications, and environmental sealing to IP65, the OPI1268S Series can be specified by our customers for a wide range of applications in potentially hazardous environments that require high voltage isolation.”

The OPI1268S Series optoisolator is comprised of a high-efficiency GaAIAs LED with a peak wavelength of 850nm, optically coupled to a photodiode that detects incoming modulated light and converts it to a proportionate current.It also features a 6-axis load rating of 10GRMS, which is important for transportation applications.

It is designed for high voltage power isolation in applications requiring sealing against dust and liquids, as well as in electrical equipment in potentially explosive atmospheres, such as transportation systems, hybrid vehicles, medical devices, and industrial control/safety systems.
