USING THE OPB350C125Z WITH THE OCB100CZ
Note: The above discussion of the OCB350 series also applies to
using the wired OPB350W series and the OPB350C125Z with the
OCB100Z.
Connect the OCB100CZ to a power source as described on page 7
“Powering up the OCB100CZ”.
Plug the OPB350C125Z connector into the 4 pin Molex mating
connector on the OCB100CZ , and then apply power to the circuit.
Adjust the phototransistor emitter load resistor to equal approxi-
mately 2.5Kohm (RL @ 2.5K) by placing the shorting bar on the board
betweens pins 1 & 2 (see table on pg. 9) of the header. Calibrate the
sensor by momentarily grounding pin 4 of connector J1 by touching ²¹
the green wire of the mating connector to the black wire (ground) of
the mating connector.
A short length of 1/8” clear tubing is included in the OCB100-KIT.
Try the following experiment. Snap the tubing into place in the
optical path of the OPB350C125Z. Calibrate the sensor. Insert water
into the tubing sample. The blue light on the OCB100CZ should
light when water is present in the optical path, and no LED should be
lit when water is not present.
