SLOH49E-9

SLOH49E Hall Effect Linear Sensor Introduction SLOH49E Linear Hall-effect sensor is small, versatile device that is operated by the magnetic field from a permanent magnet. 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. The sensor Interfaces with many electrical components without buffering. It includes thin film resistors to provide increased temperature stability and accuracy. The linear Hall-effect sensor has an operating temperature range of -40 °C to 150°C, appropriate for consumer, industrial and medical environments. The sensor is available in 2 package styles, which are TO92 and SOT23.
