Honeywell's SS360NT/SS360ST/SS460S high sensitivity, bipolar latching, digital Hall-effect sensor ICs are small, sensitive, and versatile devices operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to alternating north and south poles. The SS360NT is turned ON by a north pole, while the SS360ST and SS460S are turned ON by a south pole. They offer reverse polarity protection, deliver a stable output over a -40°C to 150°C (-40°F to 302°F) temperature range, and can accept any DC supply voltage from 3 to 24 VDC.
| Features |
|
|
- Bipolar latching magnetics
- Makes these products well-suited for accurate speed sensing and RPM (revolutions per minute) measurement
- High sensitivity
- Operate from only 30 Gauss typical, at 25°C (77°F) and 55 Gauss maximum over the full -40°C to 150°C (-40°F to 302°F) temperature range, allowing for the use of smaller magnets or a wider air gap

|
- Fastest response time
- Provides for more efficiency in commutating a brushless DC motor and offers a clean output signal due to no chopper stabilization
- Small, leaded, flat TO-92 style package (SS460S)
- Allows for a compact PC board layout
- Wide operating voltage range of 3 to 24 VDC
- Allows for potential use in a wide range of applications
