TNC Connectors
TNC Connectors are threaded RF coaxial connectors developed in accordance with MIL-C-39012 and QMB415-92 requirements. Designed for stable signal transmission and reliable mechanical locking, this series is widely used in RF equipment, coaxial cable assemblies, test instruments, and communication systems.
Product Overview
The TNC series covers a broad range of connector structures and assembly configurations, including straight types, right-angle types, bulkhead versions, panel-mount versions, cable-specific parts, and adapter-style components. Our product range includes families such as TNC-JB, TNC-JW, TNC-KF, TNC-KY, TNC-50KFD, TNC-50KWFD, TNC-50KYD, TNCM, TNCS, NTNC, and related variants.
Compared with push-on RF interfaces, the threaded TNC structure provides stronger anti-vibration performance and more secure mating stability. This makes the series suitable for environments where mechanical reliability, signal consistency, and repeated connection cycles are important.

FAQ
1. What is a TNC connector?
TNC stands for Threaded Neill-Concelman, a 50Ω threaded RF coaxial connector upgraded from BNC. It supports up to 11GHz with reliable threaded locking for high-vibration environments.
2.What’s the difference between TNC and BNC connectors?
The core difference between tnc and bnc connector is locking structure: TNC uses screw threads while BNC uses bayonet lock. TNC delivers higher frequency performance and stronger anti-loosening capability.
3. Do you supply custom TNC cable assemblies?
We offer custom tnc connector with cable matched to RG58, LMR400, semi-rigid cables, with straight or right-angle terminations.
4. Can TNC connectors be used with other RF connector types?
Yes. Common adapter solutions include TNC to BNC connector, BNC to TNC connector, TNC to SMA connector, and SMA to TNC connector.
