UHE4913G-AE3-R from UTC Unisonic Tech, 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	VOUT	output	Digital output indicating magnetic switch state. High when no magnetic field (or
2	VDD	power_in	Positive supply input. Operating range 2.4V to 5.5V (typ 2.7V); absolute max 5.5V. Average supply current IDD(AVG) typ 3μA (max 20μA) due to duty-cycled sampling (Duty Cycle typ 0.04%).
3	GND	power_in	Ground reference for supply and output.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`uhe4913g-ae3-r.step`	59 KB	You want the bare part, or you mark your own boards.
`uhe4913g-ae3-r-etched.step`	2.1 MB	You want the part with `UHE4913G-AE3-R` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 531 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.
