SS340RT and SS440R
Series
Unipolar Hall-Effect Digital
Position Sensors
DESCRIPTION
The SS340RT Series and SS440R Series 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 single pole: North
(SS340RT Series) or South (SS440R Series).
These unipolar sensors are supplied in three different magnetic
sensitivities to meet a wide range of potential applications. The
SS341RT and SS441R offer the highest sensitivity, with a
typical operating point of 85 G at 25 °C [77 °F]; the SS343RT
and SS443R offer medium sensitivity with 125 G typical at
25 °C [77 °F]; the SS349RT and SS449R offer the lowest
sensitivity, requiring 350 G typical to operate at 25 °C [77 °F].
FEATURES/BENEFITS
•
•
•
•
•
•
Subminiature package size (SS340RT Series) supplied on
tape and reel allows for a compact design with automated
component placement, helping to reduce manufacturing
costs
Simple activation from a single pole and multiple magnetic
sensitivities (high, medium and low) make this product
suitable in a variety of potential motion control, lid closure
detection, and displacement sensing applications
Low voltage 3 V 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, from -40 °C 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
SS340RT Series is available in the miniature SOT-23 surface
mount package; the SS440R is available in the leaded, flat TO-
92-style package. The SS340RT’s small size requires less PC
board space, allowing it to be used in smaller assemblies. Its
3 V capability allows for use in low voltage applications,
promoting energy efficiency.
The SS340RT Series is available on tape and reel (3000 units
per reel); the SS440R Series is available in a bulk package
(1000 units per bag).
