Overview
The TNC (Threaded Neill Concelman) connector is a threaded version of the BNC, offering secure, vibration-resistant connections for RF and microwave applications. Its 7/16-28 threaded coupling provides reliable mating and stable performance, even in demanding environments. Standard TNC connectors operate up to 11 GHz, while precision types reach 18 GHz, with 50 ohm and 75 ohm variants available. Known for low signal loss and durability, TNC connectors are widely used in telecommunications, antennas, WLAN, test equipment,smart meters and remote monitoring devices,robotics and industrial automation requiring RF links and military systems. Compact and rugged, the TNC connector delivers consistent electrical performance and is ideal for both indoor and outdoor applications.

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.
ROHS & REACH Compliance
Our products fully comply with ROHS & REACH regulations.

Body: Brass, stainless steel
Insulator: PTFE, PEEK
Contacts: Brass, phosphor bronze, beryllium copper
Other: Aluminum, titanium alloy
What is impedance, and why is 50 Ω or 75 Ω important?
Impedance matching prevents signal reflection and power loss. 50 Ω: Standard for RF communication, test equipment, aerospace, defense. 75 Ω: Standard for broadcast, video, and cable TV applications.
What materials are RF connectors made of?
Body: Brass, stainless steel, or beryllium copper (with nickel, gold, or silver plating). Insulator: PTFE, PE, or advanced low-loss dielectrics. Contacts: Gold-plated brass or beryllium copper for low resistance and durability.
Are RF connectors weatherproof?
Some RF connectors are designed with gaskets and sealing (e.g., N-type, 4.3-10) for outdoor telecom, antennas, and harsh environments. Indoor lab connectors (e.g., SMA, BNC) are usually not weatherproof unless specified.
What’s the difference between male and female RF connectors?
Male: Has a center pin and usually an outer thread or bayonet. Female: Has a receptacle (socket) for the center pin and matching thread. Some connectors (like SMA) can be confusing because “reverse polarity” (RP-SMA) swaps pin/socket configuration.
