DESCRIPTION
The UTC UHS351 sensor is small, multipurpose digital Hall-effect
device which is operated by the magnetic field from a permanent
magnet or an electromagnet. It is designed to respond to either a
North pole or a South pole.
This omnipolar sensor designed to meet a extensive range of
possible applications is flexible and sensitive device. The UTC
UHS351 has a typical operating point of 85 G at 25 °C. Because of
being operated by a North pole or a South pole, They do not require
the magnet polarity to be identified, which makes the installation
easier and potentially reduces the system cost.

FEATURES
* Simple activation from a North pole or a South pole and sensitive
magnetics makes this omnipolar product suitable in all kinds of lid
closure detection, potential motion control, and displacement
sensing applications
* Built-in reverse polarity protection prevents the device from
potential damage during installation
* Low voltage 3V ability helps reduce power consumption
* Thermally balanced integrated circuit provides for stable operation
over a wide temperature range of -40° ~ 150 °C
