SS340RT and SS440R
Series
Unipolar Hall-Effect Digital
Position Sensors
DESCRIPTION
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 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].
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).
FEATURES/BENEFITS
POTENTIAL APPLICATIONS
•
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]
•
•
Door or lid closure detection
Speed and RPM (revolutions per minute) sensing in
fitness equipment
Flow rate sensing in industrial processes, appliances, or
water softeners
Damper or valve position control in industrial, HVAC or
residential or commercial applications
Robotic control (cylinder position monitoring)
Float-based fluid level sensing
Displacement sensor in hospital beds or medical
equipment
Medication bin monitor on portable drug carts
Printer head position sensing

Note 1: The magnetic field strength (gauss) required to cause the switch to change state (operate and release) will be as specified in the magnetic
characteristics. To test the switch against the specified magnetic characteristics, the switch must be placed in a uniform magnetic field.
NOTICE
Absolute maximum ratings are the extreme limits that the device will withstand without
damage to the device. However, the electrical and mechanical characteristics are not
guaranteed as the maximum limits (above recommended operating conditions) are
approached, nor will the device necessarily operate at absolute maximum ratings.
