THE AOD155A OPTOCOUPLER WITH AN OPEN OPTICAL CHANNEL

ÒU 3 U 6629765.007

                       MAIN TECHNICAL CHARACTERISTICS           

Sum of absolute values of difference in photosignals voltage between the two optocoupler photodiode responsive elements within the operating distance of 4,5 ± 1 mm from the reflecting surface, mV, not less than, the optocoupler being turned about the zero position through an angle of:

-         ± 0,5 ^î                                                                                                                         80

-         ± 2 ^î                                                                                                                           300

Relationship of absolute values of the two optocoupler photodiode responsive elements’ photosignals, the optocoupler being turned about zero position through an angle of ± 0.5 ^î, per-unit:

-         not less than                                                                                                              0.8

-         not over                                                                                                                     1.3

 Change of the zero position over the operating distance range of 4.5±1 mm from the reflecting

surface,   mV, not over                                                                                                                10

            Optocoupler back-biased mode of photovoltaic detector operation,

bias voltage, V, not over                                                                                                             15

Dark current of each of the two optocoupler photodiode responsive elements

 at bias voltage of 15 V and temperature of  20 ^îÑ, À, not over                                              7õ10^-8

Operating current of the LED, mÀ,.                                                                    from 25 to 35

Weight, g, not over                                                                                                          2

Construction: metal-to-glass package, transparent  acrylic plastic output (input) window with a lens.

A two-element photodiode and a LED are housed in the optocoupler package.

The photodiode detects a light signal of the LED, reflected from the surface opposite to the output (input) window beyond the inside volume of the optocoupler.

OPERATING CONDITIONS

Operating emperature range, ^îÑ,                                                                          from 0 to 55

Relative air humidity, %, at temperature,                                                          up to 80 at 25

RELIABILITY CHARACTERISTICS

Failure rate 1õ10^-5  during operating age of  5000 h at confidence coefficient  0.6.

Ninety-percent quality keeping period is not less than 10 years.
