Coaxial connector TNC 50 Ω Ventev CON-05-400-CP — TNC male, Ø 1.45 cm, width 34.2 mm

Ventev CON-05-400-CP is a 50 Ω coaxial TNC connector with a male TNC interface designed for RF signal connections in communications equipment, antennas and test instruments. The connector features a compact body with a diameter of 1.45 cm and width of 34.2 mm, and a lightweight construction suitable for inline installations and cable assemblies. It provides a threaded coupling for secure mechanical and electrical connection in systems that require 50 ohm impedance.

Advantages

The TNC male design delivers reliable threaded mating and stable impedance matching for RF paths. Its brass housing with silver plating offers good electrical conductivity and corrosion resistance for typical indoor and sheltered outdoor use. The connector’s captivated center pin design eliminates the need for soldering, simplifying installation and reducing assembly time while maintaining consistent contact performance. Compliance evaluation for RoHS reduces concerns about restricted substances in regulated installations.

Suitable for

• RF coaxial cable connections in communications equipment
• Antenna feed lines and mounting points for base stations or routers
• Laboratory and field test equipment requiring 50 Ω terminations
• Cable assemblies where a threaded, vibration-resistant connection is required

How to use

Prepare the coaxial cable according to the cable manufacturer’s strip dimensions and insert the cable into the connector body until the dielectric seats against the internal shoulder. Ensure the captivated center pin aligns with the cable center conductor and that the outer conductor makes full contact with the connector body. Thread the connector onto the mating TNC jack by hand and tighten to the recommended torque for TNC connectors to secure the connection without deforming the housing. For field installations, verify continuity and return loss with appropriate test equipment after installation.

Usage recommendations

Use the connector with cables and equipment specified for 50 Ω systems. Avoid over-tightening the threaded coupling; use a calibrated torque wrench or follow the equipment manufacturer’s guidance. Store unused connectors in a dry environment and inspect mating surfaces for contamination or damage before use to maintain consistent RF performance.
