Description
SS49E Linear Hall-effect sensor is small, versatile linear
Hall-effect device that is operated by the magnetic field
from a permanent magnet or an electromagnet. The
linear sourcing output voltage is set by the supply
voltage and varies in proportion to the strength of the
magnetic field. The integrated circuitry features low
noise output, which makes it unnecessary to use external
filtering. It also includes thin film resistors to provide
increased temperature stability and accuracy. The linear
Hall sensor has an operating temperature range of -40
°C to 85 °C appropriate for commercial, consumer and
industrial environments.
Typical Applications
Motor control
Magnetic code reading
Ferrous metal detector
Current sensing
Position sensing
