Should electronics manufacturers prioritize environmental sustainability over traditional material usage?
Amphenol RF has launched an expanded portfolio of BNC connectors and adapters that utilize PEEK insulators rather than PTFE to eliminate PFAS usage. These components are designed as drop-in replacements for existing systems and are currently available through a global distribution network.
Why it matters
The transition to PEEK reflects broader efforts to future-proof hardware as global regulations regarding PFAS-containing materials tighten. This replacement strategy allows engineers to maintain existing infrastructure performance while proactively meeting sustainability standards.
The new connectors replace traditional PTFE insulators with PEEK, a high-performance thermoplastic polymer known for chemical resistance. The components maintain established physical specs with nickel-plated brass bodies and gold-plated brass or beryllium copper contacts.
The players
Amphenol RF
A global manufacturer specializing in radio frequency interconnects, coaxial connectors, and cable assemblies for industrial and telecommunications applications.
The details
The interface design swap utilizes PEEK (polyetheretherketone) to remove PFAS (per- and polyfluoroalkyl substances) previously found in PTFE (polytetrafluoroethylene) insulators. By matching the mechanical envelope of legacy BNC parts, these connectors function as drop-in replacements that do not require board or chassis redesigns. Gold-plated beryllium copper or brass is used for the contacts to ensure signal conductivity while the nickel-plated brass body provides external environmental protection.

The Tech Race
This move reflects a industry-wide pivot as manufacturers shift away from fluorinated materials in response to international regulatory pressures. The race is now to maintain component performance parity while verifying that new material stacks, such as PEEK, meet the signal integrity demands of legacy systems.
Engineers and supply chain managers can immediately source these components through the company's global distribution network for new designs or maintenance. The drop-in compatibility ensures that these parts can replace PTFE-based connectors without requiring modifications to existing hardware workflows.
The takeaway
The move underscores that regulatory compliance is now a primary driver of mechanical component innovation. Watch for upcoming supplier technical documentation to verify if these PEEK-based designs maintain identical signal loss characteristics compared to the PTFE versions they replace.
