Inertial Aerosystems introduces three-axis magnetoresistive sensors

Keywords: Navigation, Sensors

Inertial Aerosystems has introduced a three-axis magnetoresistive sensor for applications that require orthogonal three-axis sensing. The HMC 1023 magnetoresistive sensor is small in size and uses low power (see Plate 5). Manufactured by Minneapolis based Honeywell SSEC, it is specifically designed to be affordable for high volume OEM applications such as compassing, navigation systems, attitude reference, virtual reality, traffic detection, proximity detection and medical devices. Configured as three magnetoresistive sensors in x, y, and z orientation, these highly sensitive sensors convert all three magnetic field axes to a differential output voltage capable of sensing magnetic fields as low as 85 microgauss. The patented on-chip set/reset and offset straps have been improved and now require 50 percent less power to drive the set/reset and offset functions. These sensors can be operated with a three to ten volt power supply, lowering power consumption and reducing support circuitry.

The Custom Ball Grid Array (BGA), 1mm pitch, 16-pin miniature package provides a small footprint and accurate sensor placement for othogonal three-axis sensing applications. These small devices reduce board assembly costs and improve reliability and ruggedness compared to mechanical fluxgates.
