USING THE OPB732CZ WITH THE OCB100CZ
Connect the OCB100CZ to a power source as described on page 7
“Powering up the OCB100CZ”.
Plug the OPB732CZ connector into the 4 pin Molex mating connec-
tor on the OCB100CZ , and then apply power to the circuit. Adjust the
phototransistor emitter load resistor to equal approximately 10Kohms
(RL @ 10K) by placing the shorting bar on the board betweens pins 2 &
3 (see table on pg. 9) of the header. Point the OPB732CZ at a sheet of
white paper and position its front surface about ? ” from the paper.
While holding the sensor in this position, momentarily ground the pin
4 of connector J1 by touching the green wire of the mating connector
to the black wire (ground) of the mating connector.
After approximately 2-3 seconds you should see an onboard green
LED flash three times to indicate that the sensor has been calibrated
at the distance it is held from the paper. If the unit calibrated correctly,
and you have not allowed the sensor to move from the position it was
calibrated at, there will be no LEDs lit on the calibration PCB. This
means that the LED drive has ramped up to a current level sufficient to
generate an output voltage level (V OUT ) @ to ? Vcc.
Now slowly move the sensor away from the sheet of paper until a
green LED lights on the PCB. This light indicates that V OUT has dropped
to 1/3 Vcc or less. As you move the sensor closer to the paper, this
green LED will go out and then come back on at a distance very close to
the surface of the paper. At some distance between the two distances
OPTEK gives you the tools to help you take your ideas to market.
