SS449R product

SS449R

Magnetic Sensors - Switches (Solid State)

Hall EffectUnipolarIndustrialSensor

The SS449R is a unipolar digital Hall-effect sensor IC from Honeywell, optimized for South pole detection in industrial environments.

Best for

  • Industrial motion control
  • Speed and RPM sensing
  • Position monitoring

Avoid if

  • High-sensitivity requirements (use SS441R instead)
  • Surface-mount assembly requirements (use SS349RT instead)

Check before use

  • Magnetic field strength at the sensor location
  • Pull-up resistor sizing for the open-collector output
