Product Overview

XL-ITR8402 is a XINGLIGHT transmissive photoelectric switch in the LED category. Its internal construction combines an infrared emitting diode with an NPN silicon phototransistor, packaged side by side on a converging optical axis for transmissive optical switching.

The input emitter has a 940 nm peak wavelength at IF=20 mA and Ta=25°C. Electrical limits include 75 mW emitter power dissipation, 50 mA continuous forward current, 1 A peak forward current with pulse width ≤100 us and 1% duty cycle, and 5 V reverse voltage. Forward voltage is specified across 20 mA, 100 mA pulse, and 1 A pulse operating points.

The detector side is rated for 75 mW power dissipation, 30 V collector-emitter voltage, 5 V emitter-collector voltage, and 10 mA collector current at Ta=25°C. Switching characteristics include 15 us typical rise time and 15 us typical fall time under the stated VCE, IC, and load conditions.
