Ametek Dixson has expanded its precision instrumentation and cluster product lines to include a data bus compass module. The company says the compass is a highly accurate sender unit featuring a built-in two-axis magnetic sensor that converts data to a 360-degree value broadcast over an SAE J1587/J1708 vehicle data bus, providing a solution for all vehicle compass applications that can be integrated easily with NGI products or other displays.
The unit meets all SAE J1455 and J1113 requirements for vehicular instrumentation, according to Ametek Dixson, and is developed to withstand the harsh conditions encountered in the heavy-vehicle and construction industries. The module contains a six-pin, self-locking, sealed Packard Metri-Pack connector in a compact, robust and environmentally sealed polymer package. A built-in calibration routine is designed to compensate for local magnetic field distortions and accept a declination angle input to provide a true geographic north heading.
The compass is designed to be mounted in several orientations to provide flexibility in vehicle applications. For more information, go to www.ametek.com/dixson.
