SS340RT / SS440R Series
The HoneywellSS340RT Series and SS440R Series sensors 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 Series) or South ( SS440R Series).
These unipolar sensors are supplied in three different magnetic sensitivities to meet a wide range of potential applications. The SS341RT and SS441R offer the highest sensitivity, with a typical operating point of 85 G at 25 °C [77 °F]; the SS343RT and SS443R offer medium sensitivity with 125 G typical at 25 °C [77 °F]; the SS349RT and SS449R offer the lowest sensitivity, requiring 350 G typical to operate at 25 °C [77 °F].
These Honeywell sensors are available in two package styles. The SS340RT Series is available in the miniature SOT-23 surface mount package; the 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 V 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).
