AH49HZ3-G1

AH49HZ3-G1 is a small, versatile linear hall-effect device that is operated by the magnetic field from a permanent magnet or an electromagnet. The 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 components. It also includes precision resistors to provide increased temperature stability and accuracy. Applications include current sensing, motor controls, position sensing, magnetic code reading, ferrous metal detectors, vibration sensing, liquid level sensing, and weight sensing.
