Honeywell Sensing and Control SS311PT/SS411P Bipolar Hall-Effect Digital Position Sensors

The new SS311PT and SS411P Bipolar Hall-Effect Digital Position Sensors include a built-in pull-up resistor that eliminates the customer having to purchase an external resistor for many applications, reducing total system cost. These sensors utilize a downsized integrated circuit, resulting in lower costs for customers, as well as a low 2.7 Vdc supply voltage that allows for use in low voltage applications. The SS311PT is a subminiature SOT-23 surface mount package supplied on tape and reel. The SS411P is a small, leaded, flat TO-92 style available in bulk packaging. These devices are designed to respond to alternating North and South poles in high-volume, cost-sensitive rotary sensing applications.
