HX6278KUA from HUAXIN, 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 | VDD | power_in | Supply input; the datasheet gives an operating supply range of 3 V to 24 V, with an absolute maximum VDD of -0.3 to 27 V. |
| 2 | GND | power_in | Ground terminal of the Hall switch. |
| 3 | Output | output | Output of the switch transistor, which turns on in the presence of a sufficiently strong south-pole field on the marked face; the output voltage is rated 0.5 to 24 V and the output current up to 50 mA. |
