Reference PDF for the TCRT5000 reflective optical sensor, 310 KB, without a variant suffix in the name. The part combines an infrared emitter and phototransistor in a leaded package with a daylight filter, used in obstacle and line-tracking modules. Use the sheet for pinout, current limits, collector current curves and recommended reflector distance. Compare it with the TCRT5000L long-lead version if lead length matters. Check the emitter series resistor and comparator stage when a module stops detecting.
