Built-in pull-up resistor easily interfaces with
common electronic circuits without adding
external components, helping to reduce
total system cost. 2.7 Vdc to 7 Vdc supply
voltage range allows use in low voltage
applications, promoting energy efficiency.
Subminiature package size (SS311PT)
allows for compact design. SS311PT is
available on tape and reel for high volume,
automated component placement, helping
to reduce manufacturing costs. Potential
applications include speed and RPM
sensing, brushless dc motor commutation,
tachometer, counter pickup, motor and
fan control, flow-rate sensing, and robotics
control.
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.
SS345PT/SS445P.
Features: unipolar magnetics
• Subminiature package size (SS345PT)
• Tape and reel packaging (SS345PT)
• Small, flat TO-92-style package (SS445P)
• Simple activation from a North pole
(SS345PT) or a South pole (SS445P) • Low
voltage 2.7 V capability • Built-in pull-up
resistor
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.
SS351AT/SS451A.
Features: Omnipolar magnetics
• Subminiature package size (SS351AT)
• Simple activation from either South pole
or North pole • Low voltage 3 V capability
• Built-in reverse polarity protection
• Thermally balanced integrated circuit
over full temperature range
Benefits: Available in two package styles:
SS351AT in the subminiature SOT-23
surface mount; the SS451A in the leaded,
flat TO-92-style. 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. 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
cost. 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.
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.
SS361cT/SS461c.
Features: Enhanced sensitivity • Bipolar
latching magnetics • Subminiature
package size with tape and reel
packaging (SS361CT) • Small, flat TO-
92-style package (SS461C) • Simple
activation from a North pole (SS361CT) or
a South pole (SS461C) • Built-in reverse

Benefits: Enhanced sensitivity allows
operation from only 50 G typ. at 25°C
[77 °F], 80 G max. at 60 °C to 85 °C [140
°F to 185 °F], and 95 Gauss over the full
temperature range of -40 °C to 125 °C [-40
°F to 257 °F], allowing the use of smaller,
potentially lower-cost magnets or wider
air gaps. Wide operating voltage range
of 4 Vdc to 24 Vdc for use in wide range
of potential applications. Subminiature
package size (SS361CT) 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 (SS361CT) allows
for automated component placement,
helping to reduce manufacturing costs.
Small, flat TO-92-style package (SS461C)
is also available. Built-in reverse voltage
capability enhances protection of sensor
and circuits with which it is used. Bipolar
latching magnetics respond to alternating
North and South poles, making these
products well-suited for accurate speed
sensing and RPM measurement. Potential
applications include tachometer, counter
pickup, motor and fan control, flow-rate
