Single Emitter Bar Code Optic Head OTBC-04XX Series (OTR480/490/482) FEATURES: • • • • Single Emitter Bar Code / Fine Line Sensor Better than 0.010” Resolution Compact Size Easily Ganged for Multiple Channels PRODUCT DESCRIPTION The OTBC-04XX series combine a single emitter with a phototransistor in a compact low cost package containing a lens and aperture. The OTBC-0480 has a 940 nm infrared emitter and a phototransistor. The OTBC-0490 has a 660 nm visible red emitter and a phototransistor. The OTBC-0482 has a 940 nm infrared emitter and a phototransistor with an ambient light filter, for use in high ambient light conditions. These devices are easily ganged for multi-channel applications. Consult factory for custom apertures, emitters, or sensors.

This circuit is recommended for typical bar code or fine element sensing applications using the OTBC-04XX series optic heads. The first amplifier servers as a current-to-voltage amplifier (transimpedance). The second part of the circuit provides positive and negative peak detection. The peak voltages are temporarily stored in the 0.1 µF capacitors. The comparator reference is approximately 45% of the peak-to-peak amplitude. This, in effect, provides an adaptive threshold to the comparator based on the voltage peaks of the incoming signal. The 2.2 MΩ resistor on the last stage (indicated with an *) sets the positive feedback, and combined with the 10 kΩ input resistor the hysterisis is set to approximately 25 mV. Setting the 2.2 MΩ resistor to 100 kΩ will increase the hysterisis to 500 mV, but response will be sacrificed. Vout is low for reflectance and high (+5V) for no reflectance (i.e., sensing a dark mark).
