SS340RT/SS440R Series.
Features:
Unipolar magnetics: SS340RT
responds to North pole; SS440R responds
to South pole • Subminiature package size
(SS340RT) • Multiple magnetic sensitivities
(high, medium and low) • Low voltage
3 V capability • Built-in reverse polarity
protection • Thermally balanced integrated
circuit over full temperature range
Benefits:
Supplied in three different
magnetic sensitivities to meet 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’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). Potential
applications include door or lid closure
detection, speed and RPM sensing in fitness
equipment, flow rate sensing, damper or
valve position control, cylinder position
monitoring, float-based fluid level sensing
and printer head position sensing.
Benefits:
Subminiature package size
(SS345PT) uses less space on the PCB
than standard Hall-effect sensor packages
such as TO-92 or SOT-89, allowing for
use in smaller assemblies. Tape and reel
packaging (SS345PT) allows for automated
component placement, helping to reduce
manufacturing costs. Small, flat TO-92-style
package (SS445P) is also available. 2.7
Vdc to 7 Vdc capability allows for use in
low voltage applications, promoting energy
efficiency. Built-in pull-up resistor can easily
interface with common electronic circuits
without adding external components,
helping to reduce total system cost. Simple
activation from a North pole (SS345PT) or a
South pole (SS445P). Potential applications
include speed and RPM sensing in fitness
equipment, flow rate sensing in appliances
and industrial processes, displacement
sensor in hospital beds and medical
equipment and medication bin monitor on
portable drug carts.
integrated circuit provides for stable
operation over a wide temperature range.
Potential applications include speed and
RPM (revolutions per minute) sensing in
fitness equipment, magnetic encoder for
building access, damper or valve position
control in HVAC (heating, ventilation and
air conditioning) equipment, flow rate
sensing in appliances and industrial
processes, robotic control (cylinder position
monitoring), displacement sensor in
hospital beds, and medical equipment.
SS360nT/SS360ST/SS460S.
Features:
Fastest response time in its
class • No chopper stabilization • High
sensitivity • Latching magnetics • Sub-
miniature, SOT-23 surface mount package
(SS360NT/SS360ST) supplied on tape
and reel • Small, leaded, flat TO-92-style
package (SS460S) • Wide operating
voltage range of 3 Vdc to 24 Vdc • Built-in
reverse voltage • Durable design
• RoHS-compliant material meets Directive
2002/95
Benefits:
Fastest response time in its class
provides more efficiency in commutating
brushless dc motors. No chopper
stabilization results in a clean output signal.
Operates 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.
Latching magnetics make these products
well-suited for accurate speed sensing and
RPM measurement; the SS360NT is turned
ON by a North pole while the SS360ST
and SS460S are turned ON by a South
pole. Small size allows for compact design
with automated component placement, as
well as compact PC board layout. Wide
operating voltage range allows for potential
use in a wide range of applications. Built-in
reverse voltage enhances the protection
of the sensor and the circuits. Durable
design allows operation up to 150 °C
[302 °F]. Potential applications include
industrial/commercial brushless dc motor
commutation, flow rate sensing and motor
and fan control; transportation speed and
RPM sensing, tachometer, counter pickup
and convertible roof position; medical
equipment using electric motors.

SS351AT/SS451A/SS551AT.
Features:
Omnipolar magnetics
• Small through-hole and surface mount
(SOT-23 and SOT-89B) packages
• Simple activation from either South pole
or North pole • Low voltage 3 V capability

Benefits:
Available in three package
styles: SS351AT in the subminiature
SOT-23 surface mount; the SS551AT in
the SOT-89B surface mount, and the
SS451A in the leaded, flat TO-92-style.
The SS351AT’s small size requires less

promoting energy efficiency. Subminiature
package size (SS351AT) supplied on tape
and reel allows for a compact design with
automated component placement, helping
to reduce manufacturing costs. Operated
by a North pole or a South pole, these
products do not require the magnet polarity
to be identified, thus making the installation
easier and potentially reducing system
