1, 2 and 3 Axis Magnetic Sensors
HMC1051/HMC1052/HMC1053
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.
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.
