Overview
SS311PT/SS411P Bipolar Hall-effect Digital Position Sensors with Built-in Pull-up Resistor DESCRIPTION The SS311PT/SS411P sensors are small, versatile digital Halleffect 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 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, highvolume, cost-sensitive, rotary sensing applications.
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.
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.
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 • 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 • RoHS-compliant materials meet Directive 002/95/EC POTENTIAL APPLICATIONS Transportation: • Speed and RPM (revolutions per minute) sensing • Tachometer, counter pickup • Motor and fan control • Brushless dc motor control Indus...
