HSC Magnetic Compass

Product overview

The HSC chip level high stability electronic compass can provide reliable three-dimensional attitude angle data for pitch, roll and azimuth. The product can produce this data when underwater, on the ground, or in the air. To do this, it adopts a magnetic interference compensation and calibration scoring algorithm, with an azimuth accuracy of 0.1°(RMS) and a working current of 6mA. According to the actual application, the user can select the spatial calibration method or plane calibration method for on-site calibration to ensure the best performance. 

The communication protocol complies with the international standard ANSI / IEEE Std 754-2019, including binary and decimal floating-point number conversion, arithmetic format, and method. Users can easily program and connect. Ceramic packaging is applied in a HSC603A / HSC603 shell, and the perpendicularity error between the bottom of the ceramic shell and the four sides is no more than 0.01mm. Two orthogonal planes can be arbitrarily selected as the installation reference; the structure is dual in-line with 5-pin; the pin material is brass with gold-plated. The structure of the HSC605B is a PCB bare board, and the lead out pin is 4 wires. The operating temperature range is - 40 ℃ ~ 85 ℃.

The HSC high stability electronic compass is suitable for applications that require high attitude measuring precision or in which there is minimal installation space. The most common application involves a hand held infrared imager, laser rangefinder, intelligent directional instrument, underwater vehicle, aerial vehicle, etc.
