Nanjing AH Elec S & T · Hall Sensor · TO-92
AH3040 from Nanjing AH Elec S & T, in a TO-92. 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 | VCC | power_in | Supply pin for the Hall switch; the datasheet gives an operating supply range of 4.5 V to 24 V and an absolute maximum supply voltage of 24 V. |
| 2 | GND | power_in | Ground pin for the Hall switch circuit. |
| 3 | Vo | output | Open-collector output that delivers the digital switching signal; the datasheet limits the output low-level current IOL to 25 mA maximum and the output reverse breakdown voltage Vce to 40 V. |
