1.GeneralDescription                                                               

The  49E  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 outputvoltage is set by the supply voltage and varies in proportion to the strength of the magneticfield. 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, appropriate for commercial, consumer, and industrial environments.
