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 Honeywells 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 Earths magnetic fields, from 120 micro-gauss to 6 gauss. Honeywells 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. Honeywells magnetic sensor solutions provide real solutions you can count on.
