HMC1001/1002/1021/1022
Technical Specifications
The Honeywell HMC100x and HMC102x magnetic sensors are one
and two-axis surface mount sensors designed for low field magnetic
sensing. By adding supporting signal processing, cost effective
magnetometers or compassing solutions are enabled. These small,
low cost solutions are easy to assemble for high volume OEM designs.
Applications for the HMC100x and HMC102x sensors include
Compassing, Navigation Systems, Magnetometry, and Current Sensing.
The HMC100x and HMC102x sensors utilize 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.
