Differential two-wire Hall effect sensor GX760 for speed detection in speedometer

Hall speed sensor is a device that converts magnetic field changes into electrical signals through the Hall effect to achieve speed detection. The components include permanent magnets, Hall elements, and amplification circuits. When the rotating mechanism drives the magnet to change the magnetic field distribution, the Hall elements will generate periodic voltage changes, which are processed into pulse outputs.

This sensor has the characteristics of fast response speed (up to microsecond level), high measurement accuracy (error less than 0.1%), and resistance to high temperature (-40 ℃~150 ℃), high humidity, and dust environment. GX760 is an active Hall sensor that is highly suitable for crankshaft applications and similar industrial applications, such as speed sensors or any speed sensor with high precision and low jitter capability. The working temperature range of this chip is -40 ℃ to 150 ℃, and it has been widely used in fields such as speedometers, crankshaft sensors, high-precision low jitter speed sensors, etc.
