Product Overview
The VF526DT is a Bipolar Latch, Dual Hall-effect Digital Position Sensor designed to provide speed and direction indication of a magnetic gradient. Its integrated circuit chip features two Hall sensing elements precisely spaced, encapsulated in thermoset molding material. This sensor is ideal for applications requiring reliable, cost-effective speed and direction detection, such as in automotive and industrial motion control systems. The built-in temperature compensation and regulator circuit ensure stable operation across a wide voltage range (3.4 Vdc to 24 Vdc) and temperature range (-40 C to 125 C), allowing direct interface with many electronic components without additional circuitry.
