TONYU · Photointerrupters - Slot Type - Transistor Output · DIP-4
DY-ITR9809 from TONYU, in a DIP-4. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode of the infrared emitting diode (940 nm), with forward voltage 1.2 V typ/1.5 V max at IF=20mA and IF absolute maximum 50 mA. |
| 2 | K | passive | Cathode of the infrared emitting diode, with reverse voltage limited to 5 V. |
| 3 | E | passive | Emitter of the phototransistor, with emitter-collector voltage limited to 5 V (BVECO). |
| 4 | C | passive | Collector of the phototransistor, with collector-emitter voltage up to 30 V (BVCEO) and collector current up to 20 mA. |

Materials and finish
As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).
| Part | Material | Colour / plating | Datasheet says | Page |
|---|---|---|---|---|
| contacts | tin | The kinked tooling scrape easily the pin of LED, where the LED bracket is rusting easily, especial expose it in moist air. To decrease the LED bracket rust, advise using plated tin LED bracket. | 10 |
