The Leica T-Mac is a Tracker-Machine wireless control sensor that can be mounted on moving robots, machines, or parts whose position(s) need to be monitored in 6DoF (Degrees of Freedom) space. The Leica T-Mac works in tandem with T-Cam equipped Leica LTD840, LTD709, LTD706, LTD800, LTD700, and the new Leica Absolute Tracker. This innovative measurement device was developed in response to the need for automation of tracking tasks where it is difficult, impossible or undesirable to have a human being holding a wireless Leica T-Probe device.

T-Mac's 6DoF solution represents the next evolution of the Leica T-products range, delivering automated position tracking of robots or machines. The T-Mac sensor was developed as a response to several customers who had modified or adapted their Leica T-Probe wireless probing device for use in automated inspection and metrology routines.  T-Mac's off-the-shelf solution operates similarly to the Leica T-Probe, but eliminates the human interface elements of the T-Probe (buttons), as well as the contact probe, and repackages the technology in a rugged machine-mountable housing.  T-Mac can also be customized for specific tracking applications. For example, an interface for precise tool exchange units like those from Sandvik Coromant can be added.

The Leica T-Mac features a special housing for easy installation, with additional reflector nests for calibration and easy orientation, plus a mechanical interface to the calibration tool. Insensitive to environmental light, the Leica T-Mac offers the largest operation measurement volume of up to 30 m (98 ft), and a wider acceptance angle than any comparable system: pitch ±45°, yaw ±45°, roll 360°.

Point rate output for the device is 1,000 points per second backed by a 2 sigma length measurement accuracy of 60 microns in a measurement volume of 15 m (49 ft). The Leica T-Mac incorporates acoustic process information feedback for ease-of-use, as well as visual feedback for power on, in-view and in-distance status, and for process information. Tracking speeds of > 1m/s can be achieved.
