Description 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 SS441R offer the highest sensitivity, with a typical operating point of 75 G at 25 °C [77 °F].
- SS343RT and SS443R offer medium sensitivity, with a typical operating point of 135 G at 25 °C [77 °F].
- SS349RT and SS449R offer the lowest sensitivity, with a typical operating point of 305 G 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). 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
| Potential 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
