The 1.6/5.6 series is a miniature European design that permits dense connector packing, making them ideal solutions for applications where space limitation is a factor.

The Amphenol 1.6/5.6 series performs at 75 Ω up to 1 GHz. The 1.6/5.6 connectors have two coupling versions: threaded and push-pull. The threaded coupling version provides positive, familiar mating, while the push-pull coupling version allows quick installation.

This series complies with DIN 47295, DIN 41626, DIN 47297, NFC 93-569, NFC 93-570, IEC 169-13, and the CECC 22230 standards.
