PNI will continue to build and support these TCM products, but for new designs, the High-Performance Digital Compass or the V2Xe 2-axis compass module products are recommended. The legacy TCMs include the TCM2.5, TCM2.6, TCM3, and TCM5.
The TCM family of sensor modules combines PNI's patented magneto-inductive sensors with a 3-axis MEMS accelerometer in a single temperature- and noice-stabilized design that's inherently free of offset drift. Using PNI's proprietary hard- and soft-iron correction algorithms, PNI TCMs calibrate out most magnetic anomalies for repeatable, high-resolution measurement across a broad range of navigation ann tracking applications.
Even in the most demanding conditions and environments, PNI TCMs deliver unmatched performance, making them ideal for application such as high performance ROV navigation, targeting systems, GPS system navigation, vehicle sensing and tracking, drilling and downhole applications, robotics and more.

1 Using standard (full range) calibration method
2 The maximum sample rate is dependent on the strength of the magnetic field and typically will be from 25Hz to 32Hz
3 Operation at slower sample rates will reduce power consumption
