DESCRIPTION
The SS351AT and SS451A sensors are small, versatile digital
Hall-effect devices that are operated by the magnetic field from
a permanent magnet or an electromagnet. They are designed
to respond to a either a North pole or a South pole.
These omnipolar sensors are sensitive and flexible devices
designed to meet a wide range of potential applications. The
SS351AT and SS451A have a typical operating point of 85 G
at 25 °C [77 °F]. Because they can be operated by a North
pole or a South pole, they do not require the magnet polarity to
be identified, thus making the installation easier and potentially
reducing the system cost.
FEATURES
Subminiature package size (SS351AT) supplied on tape
and reel allows for a compact design with automated
component placement, helping to reduce manufacturing
costs
Simple activation from a North pole or a South pole and
sensitive magnetics make this omnipolar product suitable
in a variety of potential motion control, lid closure
detection, and displacement sensing applications
Low voltage 3 Vdc capability helps reduce power
consumption
Built-in reverse polarity protection protects the device from
potential damage during installation
Thermally balanced integrated circuit provides for stable
operation over a wide temperature range of -40° to
150 °C [-40 °F to 302 °F]
RoHS-compliant materials meet Directive 2002/95/EC
These sensors are available in two package styles. The
SS351AT is available in the subminiature SOT-23 surface
mount package; the SS451A is available in the leaded, flat TO-
92-style package. The SS351AT’s small size requires less PC
board space, allowing it to be used in smaller assemblies. Its
3 Vdc capability allows for use in low voltage applications,
promoting energy efficiency.
The SS351AT is available on tape and reel (3000 units per
reel); the SS451A is available in a bulk package (1000 units
per bag).
