Inertial Aerosystems are introducing a new version of its full three-axis magnetic chip sensor, known as the Honeywell HMC 1043. This model is now available as a RoHS-compliant device. The internal change, from using eutectic solder material of 63 per cent tin to a new material of 97 per cent tin and three per cent silver, is part of Honeywell's strategy to meet EU environmental standards.
With a small size and low weight, the 1043 is suitable for use where space and weight are at a premium. Designed for high-volume magnetometry and magnetic compass applications, it can be used in GPS receivers, robotics, security equipment, mobile phones, disability aids and process monitoring.
By using established anisotropic magnetorestive technology, the product is claimed to have many advantages over fluxgate magnetic sensors, such as being sensitive to low fields and having low hysteresis. Requiring only 2V DC and with its low-noise passive element design, it is compatible with battery-powered operations. It can also be used in strong magnetic environments, and has stray magnetic field compensation, low noise and patented set/reset straps. It is available in tape-and-reel packaging for ease of high-volume assembly.
