4.3-10 Connectors

4.3-10 Connectors

Amphenol RF offers a full range of 4.3-10 connectors and adapters, which are engineered for the wireless market and are ideal for applications requiring low passive intermodulation or PIM.

4.3-10 connectors offer the same, robust design as 7-16 connectors but are smaller and up to 40% lighter, allowing for much more dense, lighter weight applications. These designs are IP67 compliant when mated to protect against dust and water ingress for outdoor applications, and provide excellent VSWR performance up to 6 GHz. Separate electrical and mechanical components yield very stable PIM performance regardless of coupling torque, allowing for easier installation. Silver plated contacts and White Bronze plated bodies offer a high-degree of conductivity, corrosion resistance, and durability.

Features and Benefits
  • Excellent low PIM performance
  • Waterproof to IP68 when mated
  • Threaded coupling mechanism ensures secure mating
  • Available for a wide variety of cable types
  • Panel mount receptacles with various termination styles
  • Distributed Antenna Systems (DAS)
  • Base Stations
  • Wireless Infrastructure
  • Small Cells
  • Mobile Networks
  • MIMO Antennas
