OCB350L250Z, LIQUID SENSOR, PHOTOTRANSISTOR, 0.05A

The OCB350 series Liquid Sensor configured to optimize the design effort needed to use a fluid sensor with the addition of self-calibration circuitry. The device is easy to use requiring only an optical device and power supply. Four lights are provided on the board that acknowledge when the device is calibrated (green LED), that the device could not be calibrated (red LED) and when the analog output has reached the logical trip higher than the calibration point (blue LED) or lower than the calibration point (green LED). The internal phototransistor load resistance can be set for three different values. A reset/clear pin is provided for remote signalling to calibrate of the system. The device comes with an OPB350L_Z, PC-Board, interface cable (OCB100-MC24) and all the necessary electronics required for sensing either transmissive or opaque fluids.

• Can identify if liquid is present in clear tubes
• Opaque plastic housing enhances ambient light rejection
• Printed circuit board mounting or 24" 26AWG wires
