DESCRIPTION

The SS39ET/SS49E/SS59ET Series Low-cost Linear Hall-

effect sensors are small, versatile devices that are 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.

Low voltage capability as low as 2.7 Vdc and reduced current

consumption of only 6 mA typically at 5 Vdc help make this

product energy efficient.

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-effect sensors have an operating

temperature range of -40 C to 100 C [-40 F to 212 F],

appropriate for commercial, consumer, and industrial

environments.

VALUE PROPOSITION
