Description 
The SS49E and SS59ET Series Economical Linear Hall-effect sensors are small, versatile linear Hall-effect devices that are 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. These linear Hall sensors have an operating temperature range of -40 °C to 100 °C [-40 °F to 212 °F], appropriate for commercial, consumer, and industrial environments.
