Belden FSNS59RCAU Connectors

The Belden FSNS59RCAU is a ProSNS RG59 coax compression connector (RCA/phono) packaged in a 25‑pack for rapid, repeatable terminations on standard RG59 cable. It uses a non‑blind entry with a split ferrule design and a polymer compression sleeve to ease insertion and minimize tool force during termination. The connector is 75 Ω and delivers a typical return loss of ≥ -20 dB up to 208 MHz, suitable for both analog and digital audio/video signals. Construction features a nickel/tin plated brass shell and center contact, a dielectric of Ethylene Propylene, and gold‑plated contact surfaces to ensure reliable signal transfer. This FSNS59RCAU is part of Belden’s Snap‑N‑Seal ProSNS family, designed to terminate RG59 coax with professional, consistent results. Compatible with standard RG59 and quad‑shield RG59 configurations, these connectors find use in AV interconnects for video and audio applications such as CCTV, home theater, and broadcast‑quality signal distribution.
