The DMC-020 is a digital magnetic compass solution for use in precision heading applications. The DMC is designed for integration into customer systems using a 3.3-voltage logic level or a standard RS232 serial data interface.

The DMC-020-2D is a two-axis precision compass with two orthogonal flax gate sensors and can be used in tilted application while 3D calibration is impossible.
The DMC-020-3D includes a MEMS accelerometer for a horizontal three-axis, tilt compensated precision compass for performance up to a ±80° tilt range.
The DMC-020-3DG version includes 3D MEMS gyro. Fusion of the sensors’ data allows to improve the compass accuracy in noisily environment and implement more reliable and user-friendly field calibration algorithm.
