Honeywell SS341RT

The SS340RT/SS440R 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: SS341RT and SS441RT offer the highest sensitivity, with a typical operating point of 75G at 25°C[77°F] SS343RT and SS443R offer medium sensitivity, with a typical operating point of 135G at 25°C[77°F] SS349RT and SS449R offer the lowest sensitivity, with a typical operating point of 305G at 25°C[77°F] These sensors are available in two package styles: The SS340RT is available in the miniature SOT- 23 surface mount package. SS440R is available in the leaded, flat TO- 92- style package. 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).
