Honeywell SS340RT SS440R Series Unipolar Hall-Effect Digital Position Sensors Owner's Manual

SS340RT and SS440R Series Unipolar Hall-Effect Digital Position Sensors

DESCRIPTION These sensors are available in two package styles. The The SS340RT Series and SS440R Series sensors are small, SS340RT Series is available in the miniature SOT-23 surface versatile digital Hall-effect devices that are operated by the mount package; the SS440R is available in the leaded, flat TO- magnetic field from a permanent magnet or an electromagnet. 92-style package. The SS340RT’s small size requires less PC They are designed to respond to a single pole: North board space, allowing it to be used in smaller assemblies. Its (SS340RT Series) or South (SS440R Series). 3 V capability allows for use in low voltage applications,

promoting energy efficiency.

These unipolar sensors are supplied in three different magnetic sensitivities to meet a wide range of potential applications. The The SS340RT Series is available on tape and reel (3000 units SS341RT and SS441R offer the highest sensitivity, with a per reel); the SS440R Series is available in a bulk package typical operating point of 85 G at 25 °C [77 °F]; the SS343RT (1000 units per bag). 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].
