SS311PT/SS411P
Bipolar Hall-effect Digital
Position Sensors with Built-in
Pull-up Resistor
DESCRIPTION
The 2.7 Vdc to 7 Vdc supply voltage range allows this device
to be used in low voltage applications. The S311PT’s very
small size requires less PCB (printed circuit board) space,
allowing it to be used in smaller assemblies.
The SS311PT/SS411P sensors are small, versatile digital Hall-
effect devices that are operated by the magnetic field from a
permanent magnet or an electromagnet, designed to respond
to alternating North and South poles.
These sensors are available in two package styles: the
SS311PT in the subminiature SOT-23 surface mount package
and the SS411P in the leaded, flat TO-92-style package.
These bipolar sensors have enhanced sensitivity which allows
for the use of smaller, often less expensive magnets. The
internal pull-up resistor often eliminates the need for external
components, further helping to reduce system cost. These
economical bipolar sensors are suited for many simple, high-
volume, cost-sensitive, rotary sensing applications.
The SS311PT is available on tape and reel (3000 units per
reel); the SS411P is available in a bulk package (1000 units
per bag).
FEATURES
POTENTIAL APPLICATIONS
Transportation:
•
Subminiature, SOT-23 surface mount package (SS311PT)
supplied on tape and reel allows for a compact design with
automated component placement, helping to reduce
manufacturing costs
Small, leaded, flat TO-92 package (SS411P) often allows
for more space on the PCB
Sensitive, bipolar magnetics respond to alternating North
and South poles, making these products suited for speed
sensing and RPM measurement
Built-in pull-up resistor can easily interface with common
electronic circuits without adding external components,
helping to reduce total system cost

NOTICE
Bipolar Hall-effect sensors may have an initial output in either the ON or OFF state if powered up with an applied magnetic field in
the differential zone (applied magnetic field >Brp and <Bop). Honeywell recommends allowing 10 µs for output voltage to stabilize
after supply voltage has reached 5 Vdc.

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.
