Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | Anode | passive | Anode of the infrared emitter LED. Forward voltage VF = 1.4V typ (1.7V max) at IF = 10mA. Absolute max forward current IF = 35mA; reverse voltage VR = 5V max; power dissipation PD = 70mW. Drive through a current-limiting resistor from the positive supply. |+| 2 | Cathode | passive | Cathode of the infrared emitter LED. Returns LED forward current to ground (or to the low side of the drive circuit). Paired with pin 1 (Anode) as the input side of the photointerrupter. |+| 3 | Collector | passive | Collector of the NPN phototransistor (output side). Typically tied to VCC via a pull-up load resistor; the output signal is taken here. VCEO = 30V max, IC = 30mA max, PC = 80mW max. Typical IC = 0.55mA at VCE = 5V, IF = 10mA; VCE(sat) = 0.4V max at IF = 10mA / IC = 0.1mA. Dark current ICEO = 0.5µA max at VCE = 10V. |+| 4 | Emitter | passive | Emitter of the NPN phototransistor. Normally tied to ground (common-emitter configuration). VECO = 4.5V max (emitter-collector reverse). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ROHM |+| Package | DIP-4 |+| Category | Sensor |+| Pins | 4 |++## Ordering variants++- `RPI-441C1E`++## CAD (KiCad official)++- Symbol: `RPI-441C1E`+- Footprint: `Package_DIP:DIP-4_W7.62mm`+- 3D model: DIP-4 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [ROHM datasheet](docs/rpi-441c1e-datasheet.pdf) (6 pp, sha256 `6ca10eeeb0a59d96`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
