SS340RT, SS440R Series Hall-effect digital sensor IC, unipolar, low sensitivity, flat TO-92-style package, straight standard leads, 1000 units/bag 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: SS341RT and SS441R offer the highest sensitivity, with a typical operating point of 75 G (25°C) [77°F]. SS343RT and SS443R offer medium sensitivity, with a typical operating point of 135 G (25°C) [77°F]. SS349RT and SS449R offer the lowest sensitivity, with a typical operating point of 305 G (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).
