Legacy Products TCM LEGACY
PNI will continue to build and support these TCM's, but for new designs, the TCM-XB or the Prime are recommended.
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.
Our legacy TCMs include the following models and configurations:
TCM2.5 and TCM2.6: Cost-effective, reliable compass heading with PNI ASCII Interface
TCM3: Extended tilt range and 0.5° accuracy with PNI Binary Interface.
TCM5:360° tilt-range and 0.3° accuracy with PNI Binary Interface.
TCM5LT: Compact footprint, 360° tilt-range and 0.3° accuracy with PNI Binary Interface.

TCM Module
The TCM 2.5 Interface Kit contains a TCM module, pigtail interface cable (unfinished) and CD containing manuals and evaluation software. This kit allows the user to get the module up and running in minutes. Note: the cable included in this kit is only for use with TCM 2.5 modules; other TCM 2.6/3/5 modules require a different cable.
