Description

SS695 Linear Hall-effect sensor is a small, ver-

satile 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.

Specifically, when S495 is in the zero magnetic

field conditions, the output voltage is half of the

supply voltage. When south poles approach the

S495 marking surface, the output voltage will

increase

linearly

with

the

magnetic

field

strength; on the other hand, north pole will

cause output voltage decreases linearly with the

increase in magnetic field strength. The inte-

grated circuitry features low noise output, which

makes it unnecessary to use external filtering. It

also includes thin film resistors to provide in-

creased temperature stability and accuracy. The

linear Hall sensor has an operating temperature

range of -40 °C to 150 °C appropriate for com-

mercial, consumer and industrial environments.
