Carrollton, Tex. TT electronics OPTEK Technology has developed a family of optical isolators aimed at dust-contaminated environments in industrial, medical and office equipment applications. Designated the OPI1270, OPI1280 and OPI1290 series, the isolators are used in applications that require high voltage isolation between input and output as well as signal communication over short distances.
The OPI1270 and OPI1280 series isolators feature a visible red LED and a phototransistor sensor, while the OPI1290 series isolator features a visible red LED and a Photologic totem-pole output sensor. In all three devices, the LED and sensor are housed in separate opaque molded plastic housings, which shield the optical signal from dust, and are coupled by a plastic flexible cable.
The unique design of the OPI1270, OPI1280 and OPI1290 optical isolators, with the ability to mount each end of the isolator at different locations in the system, is said to maintain excellent data transmission characteristics while being available in a variety of custom lengths. The isolators also provide high noise immunity.
The isolators feature an isolation voltage of more than 20 kV with 1.27-mm lead spacing. The power dissipation rating is 100 mW and the operating temperature range is -40°C to 100°C. Custom specifications are also available for electrical specifications, wire and cable, and connectors.
Pricing: Typical pricing starts at $3.45 each in quantities of 1,000.
Availability: Production quantity delivery, if stock is not available, is six to eight weeks.
