AH49E

Description

The AH49E 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. It also includes precision resistors to provide increased temperature stability and accuracy. The operating temperature range of these linear Hall sensors is -40°C to +85°C, appropriate for commercial, consumer and industrial applications.

The AH49E is available in standard TO92S (TYPE CJ), TO-92S and SOT-23-3 packages.
