SS443R from Honeywell, in a TO-92S. 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 | VS | power_in | Positive supply; 3 Vdc to 24 Vdc operating for the SS440R over -40 °C to 150 °C, with a -28 V to 28 V absolute maximum. |
| 2 | GND | power_in | Ground reference for the supply and the current-sinking output. |
| 3 | OUT | output | Open-collector current-sinking digital output that sinks up to 20 mA with Vsat 0.4 Vdc max when the field exceeds Bop, and is rated -0.5 V to 28 V applied output voltage. |
