HMC1001 / 1002 / 1021 / 1022 are a series of small magnetoresistive sensors produced by Honeywell. They are widely used in navigation systems, attitude reference, traffic detection, medical devices and non-contact switches. These sensors have a wide field range (up to ±6 gauss), can be configured as 1-axis or 2-axis, and are solid state devices with low cost, high sensitivity and high reliability.
This document provides technical specifications and application information for Honeywell HMC1001, HMC1002, HMC1021, and HMC1022 linear magnetic field sensors. These devices utilize magnetoresistive technology to convert magnetic fields into differential voltage outputs, suitable for navigation, attitude reference, and traffic detection applications.
