Overview

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 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 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).
