Description
SS49E Linear Hall-effect sensor is small, versa-
tile 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 out-
put, which makes it unnecessary to use external
filtering. It also includes thin film resistors to
provide increased temperature stability and ac-
curacy. The linear Hall sensor has an operating
temperature range of -40 °C to 150 °C appropri-
ate for commercial, consumer and industrial
environments.
Typical Applications
─ Motor control
─ Magnetic code reading
─ Ferrous metal detector
─ Current sensing
─ Position sensing
