## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode of the AlGaAs/GaAs 940 nm IR emitter, marked 1 on the polarity symbol; continuous forward current is 100 mA max and reverse voltage is 5 V max. |
| 2 | A | passive | Anode of the IR LED, marked +2 on the polarity symbol; VF is 1.2 to 1.6 V at IF=20 mA, so a series resistor is required. |
