Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.These Simple Devices Operate At 940Nm And Work Well For Generic Ir Systems Including Remote Control And Touch-Less Object Sensing.

The red arrow points to the ir emitter / detector. The blue arrow points to where I got it. The printed circuit board under the blue arrow would slide back and forth under that gray band, which is transparent plastic with lots and lots of very skinny black lines. That was probably how the inkjet printer kept track of the position of the print head.
The 2 ir diode pins were easy enough to figure out. That’s being powered by the fat white wire on the far left. I can’t figure out the additional 4 pins on the detector part though. Notice, that’s a total of 6 pins.
