3-Axis Magnetic Sensor
HMC1043
Advanced Information
The Honeywell HMC1043 is a miniature three-axis surface mount sensor array
designed for low field magnetic sensing. By adding the HMC1043 with
supporting signal processing, a cost effective and space-efficient 3-axis
magnetometer or compassing solution is enabled. This ultra-compact, low cost
solution is easy to assemble for high volume OEM designs. Applications for the
HMC1043 include Compassing, Navigation Systems, Magnetometry, and
Current Sensing.
The HMC1043 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR)
technology that provides advantages over coil based magnetic sensors. They
are extremely sensitive, low field, 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.
