SS361RT from Honeywell, in a SOT-23. 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	VCC	power_in	Positive supply voltage (Vs). Rated 3 Vdc to 18 Vdc (3 V to 12 V at 150 °C). Built-in reverse voltage protection; absolute maximum -26 V to +28 V.
2	OUTPUT	output	Current-sinking (open-collector NPN) digital Hall-latch output. Vsat <= 0.4 V at 15 mA (gauss > 120). Requires an external pull-up; maximum output current 20 mA, applied output voltage up to 28 V. Output leakage <= 10 uA when off.
3	GROUND	power_in	Device ground (negative supply return).

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ss361rt.step`	59 KB	You want the bare part, or you mark your own boards.
`ss361rt-etched.step`	1.6 MB	You want the part with `SS361RT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 384 faces against 69 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.
