1-Axis Magnetic Sensor
HMC1041Z
Advanced Information
The Honeywell HMC1041Z is a z-axis surface mount option designed for low field magnetic sensing. By adding the HMC1041Z to other 2-axis magneto-resistive sensors, a cost effective and space-efficient 3-axis magnetometer or compassing solution is enabled. This compact, low cost solution is easy to assemble for high volume, cost effective OEM designs. Applications for the HMC1041Z include Compassing, Navigation Systems, Magnetometry, and Current Sensing.
The HMC1041Z 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.
