Product Description
3D digital compass heading finder PCBA for antenna north seeking 3 axis azimuth sensor



HCM370B-HCM375B is a high accuracy 3D digital compass of strip shape, its width is only 1.6cm, IP67 protection grade, suitable for many harsh environment such as drilling measurement. it adopts advanced hard iron and soft iron calibration algorithm, it can provide the high precision heading value output when both pitch and roll angle at any angle within 360°. it is small and low power consumption, suitable for current miniaturization sensitive measurement system. Sealed complete item and signal board are available.

HCM370B-HCM375B integrated patented three -axis flux-gate technology. It calculates heading value in real-time by CUP, and perform heading value compensation in wide tilt range by using three axis accelerometer. It is high performance and excellent stability militarily level compass sensor. Its volume is small, power consumption is low. It could widely used in many application such as antenna installation, vehicle and integrated system, and so on.

HCM370B-HCM375B 3D electronic compass azimuth is using geomagnetic principle, so it is very important to select a minimum magnetic interference environment for installation positon. Please place and install the it away from the iron, magnets, engines and other magnetic objects as much possible as you can. Need control over 30CM distance(different magnetic interfere with the compass in different distance ) at least even there are these magnetic medium around . In order to ensure optimal measurement environment please must use the M3 anti-interference screws for installation .

Although it can compensate the moderate deviation in the stable magnetic environment, but it can not compensate the changed magnetic interference. Please pay much attention to the wire with DC will generates a magnetic field , because if the DC change then the magnetic field will also change in size . The battery also is another interference source of changing . Each installation is different, and the user must evaluate the feasibility of installation under all possible operating environment.
