Product Description
Product Overview
The Magntek MT910X is a ratiometric linear Hall-effect IC with an analog output, designed for accurate position sensing. It operates from a 3.0V to 5.5V power supply and provides an output proportional to magnetic flux density. The device offers four sensitivity options to maximize output voltage swing for various sensing ranges. It is available in SOT-23 (Thin Outline) and flat TO-92 packages, both RoHS compliant. Applications include home appliances, industrial systems, speed and position detection, magnetic encoders, and ferrous metal sensing.
