Crimp TNC-W-RP coaxial connector, no name, model TNC-W-RP/ZAC.H-155

The TNC-W-RP coaxial connector (model TNC-W-RP/ZAC.H-155) is a crimp-type, reverse-polarity TNC connector intended for terminating 50 Ω coaxial cables. It provides a compact threaded RF interface with a reversed centre contact, designed to enable secure mechanical and electrical connections in radio frequency systems. The connector is suitable for installations where space is limited and a threaded connection is preferred for vibration resistance and reliable mating.

Advantages

This crimp TNC-W-RP connector offers a consistent impedance match for 50 Ω systems and a threaded design that ensures stable mechanical retention under vibration. The reverse polarity configuration maintains compatibility with devices that require RP‑TNC mating while preventing accidental connection to standard TNC devices. Crimp termination yields repeatable electrical performance when installed with the correct crimp die and tools, supporting low loss and stable RF transmission.

Suitable for

• Termination of 50 Ω coaxial cables in radio and wireless systems
• Antenna cabling for routers, Wi‑Fi equipment and repeaters that use RP‑TNC
• Field and workshop installations requiring screw-on RF connectors
• Applications where vibration resistance and compact threaded connections are needed

Key specifications

• Connector type: Reverse polarity TNC, crimp termination
• Impedance: 50 Ω
• Interface: Threaded RF coupling for secure mating
• Termination method: Crimp (requires appropriate crimp sleeve and die)
• Suitable cable types: 50 Ω coaxial cables compatible with the crimp sleeve
• Typical use: RF signal connections for antennas and wireless equipment

How to use

Prepare the coaxial cable by stripping the outer jacket, braid and dielectric to the dimensions recommended for the connector. Slide the crimp sleeve onto the cable, insert the prepared conductor and dielectric into the connector body until the centre contact is properly positioned. Seat the braid over the connector body and slide the sleeve into place. Use the correct crimp die and calibrated crimping tool to compress the sleeve to the manufacturer’s recommended specification. After crimping, inspect the joint for tightness and clean any debris before mating with equipment. Follow standard RF assembly practices to avoid signal degradation.

Usage recommendations

Use this RP‑TNC crimp connector with compatible 50 Ω cable types and the matched crimp sleeve and die to achieve optimal performance. Verify cable dimensions and crimp specifications before installation. Avoid over‑tightening mating connectors and perform a continuity and insertion loss check after assembly to confirm good RF performance.
