Speed & Direction Hall sensor family with

Latching Hall Switches

HK70X/HK71X

The HK70X / HK71X is a versatile Hall sensor family designed for speed and direction sensing, featuring two Hall sensing elements. These sensors generate two digital signals for precise speed and direction processing. Internally, they incorporate two Hall sensing elements spaced 1.63mm apart, an integrated Hall voltage generator, a voltage regulator accommodating supply voltages from 3.8 to 30V, temperature compensation circuitry, a small-signal amplifier, and a dynamic offset cancellation system. The HK70X / HK71X family offers multiple packaging options, including flat TO-94 for through-hole mounting and SOP8 for surface mounting, all in compliance with RoHS standards.
