TCM 2.5
Note: This product is designed as a replacement/upgrade module for the TCM2-20 and TCM2-50 in existing applications. New applications should be designed using the TCM 2.6 instead of the TCM 2.5.
The TCM 2.5 is a 3-axis tilt-compensated compass-heading (also known as azimuth, yaw, or bearing angle) module with electronic gimballing to provide accurate heading, pitch, and roll measurements over a ±50° tilt range.
With built-in hard-iron correction, low power demands, and digital output, the TCM 2.5 is a cost-effective, reliable solution to measure compass heading, tilt, and calibrated or uncalibrated magnetic field intensity in three dimensions.

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.
The TCM 2.5 Evaluation Kit contains a TCM module, pigtail interface cable (unfinished), computer interface cable (finished) and CD containing manuals and evaluation software. This kit allows the user to get the module up and running in minutes. Note: the cables included in this kit are only for use with TCM 2.5 modules; other TCM 2.6/3/5 modules require different cables.
The pigtail interface cable is an 18" unfinished single ended cable with the module mating connector on one side and un-terminated wires on the other for the installed system integration. This cable is for use only with the TCM 2.5.
The computer interface cable is an 18" finished cable with the module mating connector on one side and a DB9 connector on the other for connecting directly to a serial port. This cable is for use only with the TCM 2.5.
