The Honeywell 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.
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
