Hall-effect sensor

  • 05-Jan-2009 02:29 EST

Micronas’ HAL 880 programmable linear Hall-effect sensor uses digital technology to deliver performance while offering a linear analog output for compatibility with existing sensor designs. The HAL 880 can deliver the precision and accuracy for applications such as pedal position sensing. It is also suited for headlight-adjustment systems and other applications requiring linear or angular position sensing but also for current-sensing applications. With a junction temperature range of -40 to +140°C (-40 to +284°F), HAL 880 is rugged enough for automotive as well as industrial applications. The device uses a DSP to perform sensor linearization and can compensate for the variations in the Hall effect due to operating temperature, magnetic field strength, magnet temperature, Hall-plate sensitivity, and offset voltage.
