Product Overview

XL-ITR9707 from XINGLIGHT is a transmissive photoelectric switch in the LED category. The device uses an infrared emission diode and an NPN silicon phototransistor packaged side by side on a converging optical axis inside a black thermoplastic shell.

The emitter is rated for 75 mW power dissipation, 50 mA continuous forward current, 1 A peak forward current under pulsed conditions, and 5 V reverse voltage at Ta=25°C. The detector side is rated for 75 mW power dissipation, 30 V collector-emitter voltage, 5 V emitter-collector voltage, and 20 mA collector current.

Electrical and optical characteristics include 940 nm peak wavelength, 1.2 V typical forward voltage at IF=20 mA, 10 µA maximum reverse current at VR=5 V, 100 nA maximum dark current, and 15 µs typical rise and fall times. Assembly guidance includes 260 °C lead soldering within 5 seconds, wave soldering at 240±5 °C for 6 seconds, and soldering iron use below 300 °C for no more than 3 seconds per terminal.
