OCB100CZ

The OCB100CZ circuit board is configured to optimize the design effort needed to use a reflective or interruptive device and provide a consistent output eliminating the requirement to confirm either the LED drive resistance or phototransistor load resistor to provide a consistent output steady state condition. With the OCB100, the design engineer can narrow the expected start up output state providing a device that will operate the same for years with the same start up state thus enhancing the reliability and consistence of the system. Degradation of the LED or phototransistor is compensated for each time the system is calibrated. The PCB board has a set of shorting pins allowing the user to change the phototransistor load resistor. By arranging the shorting bar to the appropriate location, the load resistance can be changed from approximately 2.5K to 27KΩ. Increasing the load resistor increases the sensitivity of the device.

• The OCB100CZ is designed to maintain the calibrated setting even if power is lost
• Faster start up without the need for calibration every time the device is initiated
• Automatic calibration circuitry for optoelectronic devices
• Calibration point 50% of Vcc
• Logic trip points either 1/3Vcc and 2/3Vcc
• Can be used with reflective or interruptive devices
• Logic and analog outputs
