IP67 Connectors provide protection from elements

February 15, 2021  Stephen Law

AMPHENOL RF BNC and TNC connector designs feature waterproof IP67 interfaces and ingress protection suitable for use in outdoor applications. The 50 Ohm connectors are manufactured from brass and beryllium copper, with durable nickel-plated bodies and gold-plated contacts. The BNCs use a bayonet style connector allowing for quick connect and disconnect with a positive locking mechanism, and the TNCs have a threaded mating mechanism ensuring mating stability and electrical performance. Waterproof sealed solutions are engineered to protect designs from outside elements and are fully tested to IP67 specifications in the mated and unmated condition. RF lines are designed to meet interface performance specifications, with the addition of internal and external sealing features. A gasket within the plug body ensures the connector is sealed in the mated condition. When unmated, O-rings within the interface ensure the connector remains IP67 rated. Adhesive lined heat shrink tubing reinforces the termination area of the connector.
