Amphenol RF’s 1.6‑5.6 connector series delivers a compact, efficient solution for applications where panel space is limited and reliable signal transmission is essential. Featuring a push‑pull or optional threaded coupling mechanism, these 75 Ω connectors are engineered for fast mating and secure connections. With a performance threshold up to 1 GHz, the 1.6‑5.6 series is widely used in broadcast, telecom and LAN infrastructure.

Designed and certified to IEC 169‑13, DIN 47295, DIN 47297, NFC 93‑570 and CECC 22230 standards, these connectors offer dependable mechanical and electrical performance. Their crimp terminations simplify cable assembly, while precision-machined bodies ensure stable impedance and low return loss during operation.

Features and Benefits
  • Miniature push‑pull or threaded coupling options enable quick and reliable connections
  • Crimp‑crimp termination streamlines cable assembly and secures contacts
  • Certified to international standards for superior electrical and mechanical performance
  • High mating cycle durability—rated for 500+ insertion/removal cycles
  • Compact design supports dense arrangements in routers, base stations and broadcast modules
Key Technical Details
  • 75 Ω impedance, optimized for broadcast and video cable systems
  • Rated up to 1 GHz frequency (performance may depend on cable type)
  • Coupling options: push‑pull or threaded for varied installation needs
  • Crimp assemblies designed for RG‑59, L910/34, L910/39, BT3002 and similar cables
  • Compliant with IEC 169‑13, DIN 47295/47297, NFC 93‑569/570 and CECC 22230 standards
Applications
  • Broadcast video systems – suitable for SDI, 3 Gb/s SDI connections where space is tight
  • Telecom gear and routers – cable-saver designs for compact modules and switch panels
  • Wireless base stations – modular cable interfaces in dense RF chassis
  • Local network systems – routing 75 Ω signals in LAN infrastructure
  • Industrial communication modules – maintain signal integrity in rugged environments
