Honeywell · Hall Switches · TO-92S
SS451A 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 | Supply voltage pin, operating range 3 V to 24 V DC (absolute maximum -28 V to 28 V), with 3.5 to 6 mA typical supply current. |
| 2 | GND | power_in | Ground (-) reference pin for the supply and the sinking output. |
| 3 | OUT | output | Current-sinking digital output that goes low (Vsat max 0.4 V at 20 mA) when a North or South pole is sensed, up to 20 mA max output current, applied voltage -0.5 V to 28 V, and 10 µA max leakage when off. |
