TCM 5LT

The TCM5LT combines a full 360 degrees of tilt compensation with transistor-to-transistor level (TTL) output — providing ultra-precise digital compass heading information and magnetometer measurements while using less power than any other tilt-compensated compass module.

The TCM5LT combines PNI's patented magneto-inductive sensors with a 3-axis MEMS accelerometer in a single temperature- and noise-stabilized ASIC that's inherently free of offset drift. And using its included hard- and soft-iron correction algorithms, the TCM5LT calibrates out most magnetic anomalies for repeatable, high-resolution measurement across a wide range of navigation and tracking applications.
