Product Overview
The XL-ITR20005 is a XINGLIGHT transmissive infrared photo interrupter in the LED category. Its device structure combines an infrared emitting diode and an NPN silicon phototransistor, packaged side by side on a converging optical axis in a black thermoplastic shell. The housing is defined as a transmissive photoelectric switch package, with dimensions shown in the outline drawing and a stated tolerance of ±0.3 mm unless otherwise specified.
Electrical characteristics are specified at Ta=25 °C for several operating points. The emitter peak wavelength is 940 nm at IF=20 mA, with forward voltage listed as typ 1.2 V and max 1.6 V at IF=20 mA. The detector side includes max 100 nA dark current at VCE=20 V and max 0.4 V collector-emitter saturation voltage at IC=2 mA and Ee=1 mW/cm2.
The part is applicable to transmissive sensing tasks such as object passage detection, slot sensing, position detection, and interrupt-based control inputs. Assembly guidance includes 260 °C lead soldering for 5 seconds at 2 mm from the body, 240±5 °C wave soldering for 6 seconds, and manual soldering below 300 °C within 3 seconds per terminal.
