HMC6042 Advanced Information
The Honeywell HMC6042 is a surface mount multi-chip module designed for low field magnetic sensing such as low cost compassing and magnetometry. The HMC6042 includes our state of the art 1042 series magneto-resistive sensors plus a precision mixed signal ASIC containing three sensor amplifiers and a compatible set/reset strap driver circuit for 2.4 to 3.6 volt operation. The ASIC plus sensors are surface mount packaged in a 3.6 by 5.0 by 1.0mm LCC that can be used stand alone for very low cost 2-axis compasses, or with the HMC1041Z to complete the magnetic sensor portion of a 3-axis, tilt compensated compass. Applications for the HMC6042 include Consumer Electronic Compassing and Magnetometry.
The HMC6042 utilizes Honeywell’s Anisotropic Magnetoresistive (AMR) technology that provides advantages over other magnetic sensor technologies. The sensors feature precision in-axis sensitivity and linearity, solid-state construction with very low cross-axis sensitivity designed to measure both 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.
