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.
