SS49E 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.
FEATURES:
1.Miniature and subminiature construction: Designed for compact designs with tight space requirements.
2.Energy efficient: Low current consumption of 6 mA at 5 Vdc.
3.Easy PC board interface: Single current sourcing output for common electronic circuits.
4.Circuit design flexibility: Voltage range of 2.7 Vdc to 6.5 Vdc.
5.Low noise output: Virtually eliminates the need for flittering.
