HallSwitch Unipolar Description

SS340RT, SS440R Series unipolar digital Hall-effect sensor IC, medium sensitivity, SOT-23, 3000 units/pocket tape and reel

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).

Features

  • Subminiature package size (SS340RT) supplied on tape and reel: Allows for a compact design with automated component placement, helping to reduce manufacturing costs
  • Simple activation from a single pole and multiple magnetic sensitivities (high, medium and low): Make this product suitable in a variety of potential motion control, lid closure detection, and displacement sensing applications
  • Low voltage 3 V capability: Helps reduce power consumption
  • Built-in reverse polarity protection: Protects the device from potential damage during installation
  • Thermally balanced integrated circuit: Provides for stable operation over a wide temperature range of -40°C to 150°C [-40°F to 302°F]
  • RoHS-compliant materials: Meet Directive 2002/95/EC

Target Applications

Industrial:

  • Door or lid closure detection
  • Speed and RPM (revolutions per minute) sensing in fitness equipment
  • Flow rate sensing in industrial processes, appliances, and water softeners
  • Damper or valve position control in industrial, HVAC and residential or commercial applications
  • Robotic control (cylinder position monitoring)
  • Float-based fluid level sensing
  • Printer head position sensing

Medical:

  • Displacement sensor in hospital beds and medical equipment
  • Medication bin monitor on portable drug carts
