The SS340RT/SS440R Series sensor ICs are small, versatile digital Hall-effect devices that are operated by the magnetic field from a permanent magnet or an electromagnet. They are designed to respond to a single pole: North (SS340RT) or South (SS440R).
These unipolar Hall ICs are supplied in three different magnetic sensitivities to meet a wide range of potential applications:
These sensors are available in two package styles:
The SS340RT’s small size requires less PC board space, allowing it to be used in smaller assemblies. Its 3 Vdc capability allows for use in low voltage applications, promoting energy efficiency.
The SS340RT Series is available on tape and reel (3000 units per reel); the SS440R Series is available in a bulk package (1000 units per bag).
