About the TCM2.5/2.6
Thank you for purchasing the TCM2.5/2.6. The TCM2.5 has been designed as a drop-in
replacement for PNI Corporation’s TCM2 family of products. The TCM2.5 uses the same board size,
interface connector, and RS-232 protocol as the TCM2 modules to allow for ease of integration with
existing systems. The TCM2.6 has all the features of the TCM2.5, but is about half the size and
weight and has an extended temperature range.
The TCM2.5/2.6 are the choice for existing applications that require compatibility with PNI
Corporation’s TCM2 family of products.
The TCM2.5/2.6 integrates 3-axis magnetic field sensing, 2-axis tilt sensing, and compass heading
into a single module. Advantages include compatibility with existing systems, low power
consumption, large signal noise immunity under all conditions, and a large magnetic field
measurement range.
The TCM2.5/2.6 combines PNI Corporation’s patented Magneto-Inductive (MI) sensors and
measurement circuit technology with a MEMS accelerometer for unparalleled cost effectiveness
and performance. The MI sensor changes inductance by 100% over its field measurement range.
This variable inductance property is used in a cost and space efficient ASIC (PNI 11096) which
incorporates a temperature and noise stabilized oscillator/counter circuit which is inherently free
from offset drift.
The TCM2.5/2.6’s advantages make it suitable for many applications, including:
Remote terrestrial antenna direction indicators
Side-scan sonar
ROV, AUV control
Survey equipment
Robotics systems
Vehicle detection
With its many potential applications, the TCM2.5/2.6 provides a command set designed with flexibil-
ity and adaptability in mind. Many parameters are user-programmable, including reporting units, a
wide range of sampling configurations, output damping, and more. We hope the TCM2.5/2.6 will
help you to achieve the greatest performance from your target system. Thank you for selecting the
TCM2.5/2.6.
