Unipolar magnetics • Subminiature package size (SS345PT) • Tape and reel packaging (SS345PT) • Small, flat TO-92-style package (SS445P) • Simple activation from a North pole (SS345PT) or a South pole (SS445P) • Low voltage 2.7 V capability • Built-in pull-up resistor Subminiature package size (SS345PT) uses less space on the PCB than standard Hall-effect sensor packages such as flat TO-92-style or SOT-89B, allowing for use in smaller assemblies. Tape and reel packaging (SS345PT) allows for automated component placement, helping to reduce manufacturing costs. Small, flat TO-92-style package (SS445P) is also available. 2.7 Vdc to 7 Vdc capability allows for use in low voltage applications, promoting energy efficiency. Built-in pull-up resistor can easily interface with common electronic circuits without adding external components, helping to reduce total system cost. Simple activation from a North pole (SS345PT) or a South pole (SS445P). Potential applications include speed and RPM sensing in fitness equipment, flow rate sensing in appliances and industrial processes, displacement sensor in hospital beds and medical equipment and medication bin monitor on portable drug carts.
