The TCM2.6 has all the features of the TCM2.5, but is about half the size and weight, making it ideal for today’s size sensitive applications. It uses the same RS-232 interface protocol, which allows for easy integration into existing systems, but has the addition of an extended temperature range of -40º to 85ºC. Features The TCM2.6 integrates 3-axis magnetic field sensing, 2-axis tilt sensing and compass heading into a single module. Advantages include protocol compatibility with existing systems, low power consumption, large signal noise immunity under all conditions, and a large magnetic field measurement range in a small package. The TCM2.6 combines PNI Corporation’s patented Magneto-Inductive (MI) magnetic sensors and a MEMS accelerometer in a single module, offering unparalleled cost effectiveness and performance. MI sensors change inductance by 100% over the wide field measurement range. This variable inductance property is used in a cost and space efficient ASIC, incorporating a temperature and noise stabilized oscillator/ counter circuit which is inherently free from offset drift. • Multiple measurement modes: compass heading, magnetic field and 2-axis tilt • High accuracy compass heading: 0.8º • High resolution compass heading: 0.1º • High repeatability: 0.1º • Wide tilt range: +/- 50º • Calibrated magnetic field measurement range: +/- 80 µT (+/- 0.8 Gauss) • High resolution magnetic field measurement: 0.05 µT (0.0005 Gauss) • Extended temperature range: -40º to 85ºC • Small size: 3.5 x 4.3 x 1.3 cm • Reliable calibration: hard-iron calibration with quality of calibration score • Low Power: < 20 mA typical current draw Applications • Backwards compatible digital interface: RS-232 • ROV/AUV’s • Remote terrestrial antenna direction indicators • Side-scan sonar • Survey equipment • Robotics systems • Vehicle detection • Weather stations Ordering Information NAME PART NUMBER TCM2.6 Module 12477 TCM2.6 Interface Kit 90012 TCM2.6 Evaluation Kit 90019 Interface kit includes: module, manual, evaluation software and 18” pigtail cable Evaluation kit includes: module, manual, evaluation software, 18” pigtail cable and 6ft finished DB-9 cable with power supply Developed by America’s premier sensor technology company.
