1-Axis Magnetic Sensor HMC1041Z

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.
