Optical Isolators
Optek Technology, Industrial Sensing & ControlRequest Info
TT electronics Optek Technology’s OPI1268 optical isolator
delivers AC and DC voltage isolation up to 16 kV while achieving digital data transmission
rates of 2 MBd. It is UL-recognized and designed for power isolation in high-voltage
PC board circuits in industrial electronics systems, medical electronic equipment
and office machines. The output integrated circuit (IC) detects the incoming optical
signal and converts it to a proportionate current, which is fed through a linear
amplifier and compensated for temperature, current and voltage, resulting in stable
digital output with an open collector inverter configuration. The device comprises
a GaAlAs LED with a peak wavelength of 850 nm, optically coupled to a Photologic
photodiode in the output IC. Packaged in an opaque plastic housing, it measures
27.94 x 6.35 x 8.89 mm and operates from —40 to 100 °C.
