SS411P - Bipolar Hall-effect Digital Position Sensors

General 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.

Key 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 com.

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.
