Product Description
The Honeywell HMC1051Z and HMC1052 are high performance magnetoresistive sensor designs on a single chip. The advantages of these patented chips include perfectly orthogonal two-axis sensing (HMC1052), ultra small size and low power capability in miniature surface mount packages.
Each of the magnetoresistive sensors are configured as a 4-element wheatstone bridge to convert magnetic fields to differential output voltages. Capable of sensing fields below 0.1 milligauss, these sensors offer a compact, low cost, high sensitivity and highly reliable solution for low field magnetic sensing.
