In Stock
The SS41F Hall Effect Sensor is a versatile, TO92 packaged digital magnetic switch designed to respond to both north and south magnetic poles [citation:1][citation:7]. This sensor features an opendrain output that switches low when a sufficiently strong magnetic field is detected, making it an essential component for position sensing, speed measurement, and ring magnet applications [citation:1][citation:4].

The SS41F is a bipolar sensor, meaning it responds to both north and south magnetic poles with hysteresis [citation:1][citation:4][citation:5]:
| Condition | Output State | Magnetic Field |
|---|---|---|
| South Pole Present (B > BOP) | LOW (0V) | Sensor triggered [citation:5] |
| North Pole Present (B < BRP) | HIGH | Sensor released [citation:5] |
> Output is opendrain only pulls to ground
