**CONNTEK** · Linear Hall Sensors · TO-92S

KTM1301TC-TO3 from CONNTEK, 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 | OUTPUT | output | Push-pull CMOS output that goes low when the magnetic field exceeds BOP and high when it falls below BRP, with a maximum output drive current of 5 mA. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | VDD | power_in | Supply input, operating over 1.8 V to 5.5 V. |
