The OCB100-KIT allows engineers to become familiar with the capabilities of transmissive, reflective, and fluid optoelectronic sensors. As shown on this page, the kit includes an automatic calibration circuit board with digital and analog outputs, a non-focused reflective switch, a wide gap slotted switch, and a fluid sensor. In addition, the calibration board can be interfaced to almost any optoelectronic sensor with a phototransistor output via the onboard Molex 70553-0038 four pin header.
