The Honeywell HMC1051, HMC1052 and HMC1053 are
magnetoresistive sensors designed for low field magnetic sensing.
Various packaging options have been created from the basic
HMC1052 sensor chip to create 1, 2 and 3-axis magneto-resistive
sensors for cost effective and small size solutions. The advantage
of the HMC105X family of sensors is in the near-perfectly
orthogonal dual sensor on a single chip with shared set/reset and
offset coils/straps included.
The HMC105X family 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 120 micro-gauss to
6 gauss. Honeywell’s Magnetic Sensors are among the most
sensitive and reliable low-field sensors in the industry. Applications
for the HMC105X family of sensors include low cost Compassing,
Magnetometry, and Current Sensing.
