SS41F from Honeywell, in a TO-92S. 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	VS	power_in	Supply voltage input, 3.8 V to 30 V DC. Provides operating power to the Hall sensor IC.
2	OUTPUT	output	Open-collector digital output. Sinks up to 20 mA when active (south pole present); requires an external pull-up resistor to VS. Output is latched by opposite-polarity field.
3	GND	power_in	Ground reference (0 V) for the sensor supply and output.

Footprint: Package_TO_SOT_THT:TO-92_Inline
3D model: TO-92S (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ss41f.step`	27 KB	You want the bare part, or you mark your own boards.
`ss41f-etched.step`	861 KB	You want the part with `SS41F` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 217 faces against 19 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
