Airmar MMC-EXT-20 Extension Cable 12-Pin - 12-Pin 20' for CHIRP MMC Cables

The Airmar MMC-EXT-20 Extension Cable 12-Pin is a purpose-built connectivity solution for marine electronics systems operating on CHIRP MMC protocols. This 20-foot extension cable serves operators, marine technicians, and tactical asset managers who require reliable data transmission between fishfinder transducers and networked display units in demanding environments. The extended length eliminates placement constraints when integrating sonar systems into vehicles, vessels, or command centers where standard cable runs fall short.

Built with dual 12-pin connectors, the MMC-EXT-20 maintains signal integrity across the full 20-foot span through shielded conductor design and precision-molded connector housings. The cable supports full CHIRP MMC protocol bandwidth without signal degradation, critical for maintaining sonar image clarity and real-time positioning data in field operations. At 2 pounds total weight, the cable remains portable and deployable without adding substantial burden to mobile tactical platforms or waterborne installations.

The Airmar MMC-EXT-20 integrates seamlessly with all Airmar CHIRP MMC-compatible transducers and display units, making it essential for operators expanding existing sensor networks or retrofitting equipment into space-constrained platforms. Marine asset managers, naval support personnel, and emergency response teams benefit from the extended connectivity range when establishing distributed sensor grids. Installation requires simple 12-pin connector interface compatibility—no tools or modifications needed for immediate deployment in field conditions.
