The Connex N connectors with screw coupling are fully interchangeable with N connectors made to the MIL-C-39012 specification. Designed for use in all systems where very good R.F. and mechanical performance is critical, whether it be at low or high frequencies. Intermodulation problems have long been a serious concern for the telecommunications market. The elimination of all nickel plating on N series connectors has gone a long way to solve this problem. Connex offers both silver-plated (no nickel undercoat on body or under 30µ gold center contact) and Nexcote-plated connectors. Nexcote is our trade name for the popular white bronze plating, and is fully compatible with all other commercial tri-alloy platings on the market. All connector bodies, unless otherwise noted, are nickel plated and all contacts are gold plated 3µ. All insulators are teflon. Silver plating is available.
