 MC-R3 – Machine Control Receiver 3

Topcon's MC-R3 is the heart of Topcon's 3D-MC system. Providing either solid brackets for permanent mounting or magnetic mounting for portability, the MC-R3 contains all of the GNSS receivers, radios, and controllers in a single "built to last" housing. A built-in MINTER panel provides status lights and function keys for easy performance verification and system checks. The MC-R3 also features an Ethernet port, increased processing power over the previous generation box, and additional valve drivers to account for the widest array of machine compatibility.

Topcon's 3D-MC can be used in combination with other grade sensors such as Sonic Trackers®, slope sensors, and laser receivers. Find out more here.

For use with Motor Graders, Bulldozers, Compactors, Scrapers and Box Blades.
