XL-ITR20001 Reflective Photoelectric Optical Switch

Specifications

Product Overview

XL-ITR20001 is a XINGLIGHT reflective photoelectric optical switch in the LED category. The device composition is an infrared emission diode paired with an NPN silicon phototransistor, arranged side by side on a converging optical axis for reflective sensing.

The emitter has a 940 nm peak wavelength at IF=20 mA and Ta=25 °C. Absolute maximum ratings include 75 mW input emitter power dissipation, 50 mA continuous forward current, 1 A peak forward current for pulse width <=100 us at 1% duty cycle, and 5 V input reverse voltage. Detector-side limits include 75 mW output detector power dissipation, 30 V collector-emitter voltage, 5 V emitter-collector voltage, and 20 mA collector current.

The package is described as a black thermoplastic reflective optical switch package, with outline dimensions shown in the datasheet and a general outline dimension tolerance of ±0.3 mm unless otherwise specified. Assembly data includes MSL 2, Pb-free and RoHS compliant status, 240 ±5 °C for 6 s recommended wave soldering, less than 300 °C for 3 s manual soldering, and 260 °C lead soldering at 2 mm from the body for 5 seconds.

Procurement Notes

When requesting a quote for XL-ITR20001, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.

If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.

For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
