How do I wire the H42B6 to an Arduino or ESP32?
The IR LED side needs a series current-limiting resistor, and the phototransistor side is read as a digital signal with a pull-up or pull-down resistor. Confirm the pin labels and output logic in the datasheet for the exact part before wiring.
What is it used for?
It detects whether an object is inside the U-slot, which is useful for counting encoder slots, homing a CNC axis or checking the end position of a moving head.
