SS566AT

Honeywell · Hall Switches · SOT-89

SS566AT from Honeywell, in a SOT-89. 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 (Vs +), rated 3.8 Vdc to 30 Vdc, absolute maximum 30 V; a capacitor between output and supply may be needed above 24 Vdc.
2 GND power_in Ground (-), the common return for the supply and the open-collector output transistor.
3 OUT output Open-collector sinking output (O), 20 mA rated continuous sink, 50 mA max, Vsat 0.4 V max, applied output voltage up to 30 V.
