Sensors

All AHS magnetic sensor active materials are made from the III-V semiconducting compounds based on Gallium Arsenide (GaAs). Multilayer structures of these compounds are deposited to atomic layer precision using the sophisticated crystal growth technique of Molecular Beam Epitaxy (MBE).

This growth method also ensures thin films of the compounds show less than 0.5% variation in composition with doping profiles accurate to ppm levels. Uniformity & repeat-ability of this high performance device material is exceptional by any standards.

Characteristics

In addition to these reference level sensitivities, other key characteristics of AHS devices include extremely low Hall voltage temperature coefficients over a wide temperature range (-100°C to +180°C); and low power consumption.

Sensors may be supplied pre-packaged or as a wafer die. Dimensions of the two popular packaging formats displayed on this page are given on the data sheets but others may be available. Please contact us to discuss your requirement.
