Coaxial Insert Connectors

Coaxial insert connectors from Amphenol RF are precision-engineered components that allow reliable signal transfer from cable to PCB or subassembly modules. Available in both plug and jack variants, these inserts support a variety of 50 Ω cable types—including RG‑58, RG‑174, RG‑316, RG‑405, and conformable microcoax—enabling versatile integration in space-constrained designs without sacrificing RF integrity. Their robust mechanical and electrical properties ensure strong contact, low loss, and consistent performance across applications.

Ideal for high-frequency and high-reliability environments, coaxial inserts simplify custom cable assembly and modular sub-system design. These inserts offer a cost-effective alternative to overmolded terminations, allowing engineers to optimize signal paths while maintaining clean, standardized connection interfaces.

Features and Benefits

• Wide cable compatibility: Supports standard RG and specialty microcoax cables
• Insertable format: Plug into modules or PCBs with consistent mechanical fit
• Precise impedance matching: Maintains 50 Ω signal integrity across interface
• Durable construction: Machined inserts with gold-plated contacts resistant to wear
• Flexible mating configurations: Various plug/jack options for blanket system design

Key Technical Details

• Cable types: RG‑58, RG‑174, RG‑316, RG‑405, conformable microcoax (e.g. 0.047″, 0.086″)
• Termination options: Straight crimp, solder versions available for different cable styles
• Insert geometry: Designed for tight die cavities in PCB/subsystem assemblies
• Contact design: Optimized for low loss and reliable return loss performance
• Deployment readiness: Ideal for custom cable harnesses or factory-installed modular units

Applications

• Wireless test and measurement – feed-through connection panels in test racks
• Embedded RF modules – modular board-to-board or cable-to-board RF interfaces
• Automotive and avionics subassemblies – compact RF inserts in sensor and antenna harnesses
• Network and broadcast submodules – field-serviceable RF blocks with coax ports
