SS443R

Honeywell · Hall Switches · TO-92S

SS443R from Honeywell, 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 VS power_in Positive supply; 3 Vdc to 24 Vdc operating for the SS440R over -40 °C to 150 °C, with a -28 V to 28 V absolute maximum.
2 GND power_in Ground reference for the supply and the current-sinking output.
3 OUT output Open-collector current-sinking digital output that sinks up to 20 mA with Vsat 0.4 Vdc max when the field exceeds Bop, and is rated -0.5 V to 28 V applied output voltage.

CAD (KiCad official)

  • Symbol: SS443R
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92S (KiCad packages3D, STEP)
  • 3D model files: ss443r-etched.step / ss443r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ss443r.step / ss443r.glb are the bare package body.
