**HX(hengjiaxing)** · Magnetic Sensors · TO-92

HX4913 from HX(hengjiaxing), 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 voltage input, operating range 2.0 V to 6.0 V (absolute maximum -0.5 to 6.0 V). |
| 2 | GND | power_in | Ground pin. |
| 3 | OUT | output | Open-drain output that turns on (low) when |B| exceeds Bop, with 100 kΩ pull-up RL recommended and saturation voltage typically 0.05 V at Io=2 mA. |
