RP-TNC Connectors
Reliable, threaded reverse‑polarity RF connectors for secure, weather‑resistant applications
Overview
Amphenol RF’s RP‑TNC connectors bring the durability and performance of standard TNC interfaces to applications requiring reverse‑polarity for enhanced tamper resistance and regulatory compliance. Their threaded coupling ensures a secure connection with excellent resistance to vibration and environmental exposure—making them a reliable RF interface.
With compatibility to operate from DC up to 11 GHz (18 GHz for extended-range designs), RP‑TNCs support demanding wireless, industrial and outdoor applications. A full lineup—including straight and right-angle plugs, panel-mount jacks and IP67-rated microcoax versions—ensures flexible deployment across systems.
