Coming in a 0.300" × 0.160" × 0.114" SMT package, OPTEK Technology’s OPB733TR reflective object sensor exhibits an optimizing detection range from 0.400" to 1". The component contains a lensed IR LED with a typical peak emission wavelength of 890 nm. The sensor uses a NPN silicon phototransistor offering output on-state collector current of 0.100 mA at 0.500" distance from the target; 20-mA forward current, VCE of 5 V, and typ. signal rise and fall time of 15 µS. The device performs in paper edge detection, automatic sensing applications, counting, sorting, and proximity sensing in industrial applications; and door and end-of-travel sensing applications. Pricing is $1.32 each in 1,000 quantities.
