2-Axis Magnetic Sensor
HMC1042L
The Honeywell HMC1042L is a high-performance, two-axis
magneto-resistive sensor. It is designed for magnetic compass
applications with capability of 0.2 degree accuracy. Stand alone or
by adding the companion HMC1041Z sensor, precision two and
three-axis magnetometry or compassing solutions are enabled. Pin
compatible with the HMC1052L; this miniature, low cost solution is
easy to assemble for high volume, cost effective OEM designs.
Applications for the HMC1042L include Compassing, Navigation
Systems, Magnetometry, and Magnetic Anomaly Detection.
The HMC1042L utilizes Honeywell’s Anisotropic Magnetoresistive
(AMR) technology that provides advantages over coil based
magnetic sensors. They are extremely sensitive, low field, low hysteresis, solid-state magnetic sensors designed to
measure direction and magnitude of Earth’s magnetic fields, from tens of micro-gauss to 6 gauss. Honeywell’s Magnetic
Sensors are among the most sensitive and reliable low-field sensors in the industry.
Honeywell continues to maintain product excellence and performance by introducing innovative solid-state magnetic
sensor solutions. These are highly reliable, top performance products that are delivered when promised. Honeywell’s
magnetic sensor solutions provide real solutions you can count on.
