Overview
The SS345PT/SS445P 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 a single North pole (SS345PT) or South pole (SS445P).
These unipolar sensors are designed to meet the requirements of a wide range of potential applications. The internal pull-up resistor often eliminates the need for external components, further helping to reduce the system cost. These economical unipolar sensors are well suited for simple, high-volume, cost-sensitive position and motion sensing applications.
The 2.7 Vdc to 7 Vdc supply voltage range allows this device to be used in low voltage applications. The SS345PT’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 SS345PT in the subminiature SOT-23 surface mount package: the SS445P is available in the leaded, flat TO-92-style package.
The SS345PT is available on tape and reel (3000 units per reel): the SS445P is available in a bulk package (1000 units per bag).
