7/16 DIN connector
Coaxial RF connectors of the 7/16 DIN variety are renowned for their strong construction and capacity to handle large amounts of power. It was created in Germany and is frequently found in systems for professional communication.
The term “7/16 DIN connector” comes from:
- 7 mm for the inner contact or 7 mm for the inner conductor diameter.
- 16 mm for the outer contact’s inner diameter or 16 mm for the mating interface’s outer diameter.
- The Deutsches Institut für Normung (DIN) is the German standards body.

Bayonet Neill Concelman BNC connector
Designed for fast and dependable connections, BNC (Bayonet Neill-Concelman) connectors are small, bayonet-style radio frequency (RF) coaxial connectors. They were first installed on military radio equipment in the 1940s, and they are now widely utilized in many different applications, such as video links and radio systems.
Origin and Naming
The Bell Labs’ Paul Neill and Amphenol’s Carl Concelman are the namesakes of the BNC connector. Usually, the bayonet locking mechanism is the “B” in BNC. Although “Bayonet Neill-Concelman” is a popular interpretation, the acronym has also been suggested historically as “Baby Neill Constant” (used by the US Navy in 1944), “Baby N Connector,” “British Naval Connector,” “Bayonet N Connector,” and “Bayonet Nut Coupling.” Carl Concelman created the C connector, whereas Paul Neill created the N connector. A patent application for the BNC, which combined elements of the N and C connectors, was also submitted in 1945 by Octavio M. Salati of Hazeltine Corporation.

Bayonet Neill Concelman BNC connector Key Characteristics and Features
Bayonet Coupling: The quick-connect/disconnect mechanism is what distinguishes BNC connectors. Two bayonet lugs on the female connector provide a safe and reliable lock by locking into a quarter-turn mechanism. A tactile “snap” is provided by this twist-and-lock mechanism to verify a strong connection without the need for equipment.
Coaxial Connection: BNC connectors are made especially to carry radio frequency (RF) signals with the least amount of signal loss possible when used with coaxial cables.
Constant Impedance: They are constant-impedance connections, which guarantee a steady impedance across the connection, which is essential for preserving signal integrity.
Dimensions: Male connectors typically have an exterior diameter of 0.570 inches (14.5 mm), while female connectors typically have an outer diameter of 0.436 inches (11.1 mm). They also come in miniature and subminiature sizes.
Voltage and Frequency: RF frequencies up to around 2 GHz and voltages under 500 volts are commonly handled by BNC connectors. Some precise designs, however, can reach 11 GHz, while 50-ohm versions can function up to 4 GHz. Usually, 75-ohm versions are utilized up to 2 GHz.
Durability: Although they function reliably at medium frequencies, they are not as durable as larger connectors in challenging outdoor conditions.
Mating Cycles: Their rating for mating cycles is usually 500.
Standardization: Standards such as CECC 22121, IEC 61169-8, and MIL-STD-348B are met by BNC connections.

BNC Connector Types
The two main impedance types of BNC connections, each appropriate for a distinct purpose, are as follows:
50-Ohm BNC Connectors:
They are the most widely utilized type for data and general radio frequency transmission.
- Applications: Equipment for amateur radio, test and measurement tools (such as signal generators and oscilloscopes), and outdated computer networks (10BASE2 Ethernet, for example).
- Frequency: Has a maximum operating frequency of 4 GHz and, in certain designs, 11 GHz.
75-Ohm BNC Connectors:
For professional audio and video communications, when reducing signal loss is essential, these are especially made.
- Applications: DS3 Telco central office applications, CCTV security systems, broadcast video equipment, professional audio-visual installations, and analogue and serial digital interface (SDI) video signals.
- Frequency: Used for frequencies up to 2 GHz in most cases.
It is not advised to mix different impedance connectors for high-frequency or high-bit-rate applications, even though 50-ohm and 75-ohm BNC connectors are technically compatible and can physically mate. Degradation and reflections of signals can result from an impedance mismatch. The impedance mismatch is insignificant at frequencies lower than 10 MHz, but it becomes increasingly important at higher frequencies.
Bayonet Neill Concelman BNC connector Applications
Many Different fields make extensive use of BNC connectors:
Video: Video feeds from analogue and serial digital interfaces (SDI) in CCTV systems, recording studios, and broadcasts.
Radio & Test Equipment: Avionics (aerospace electronics), nuclear instrumentation, amateur radio, and other test and measurement tools such as oscilloscopes and signal generators.
Networking (Older Use): ARCnet, the IBM PC Network, and the 10BASE-2 (thinnet) and 10BASE-5 (thicknet) Ethernet networks were among the older LAN technologies that historically made extensive use of BNC connectors.
Telecommunications: BNC connectors are required for electrical and mechanical connections between telephone company equipment and Data Terminal Equipment (DTE) that operates at E1 data rates, according to the ITU-T G.703 standard.
Cable Television (CATV).

Mating and Installation
The connection is locked firmly by inserting a male BNC connector into a female connector and rotating it around 90 degrees. One of the following techniques is commonly used to terminate connectors onto coaxial cables:
- Crimp: Using a crimping tool to fasten the connector’s ferrule onto the cable’s braided shield is the most popular and dependable technique.
- Solder: A stronger connection is provided by the centre pin, which is soldered to the cable’s core conductor but is more challenging to install.
- Twist-on/Compression: The connection is merely twisted onto the cable in this tool-free field installation technique.
In dense patch panels, a BNC inserter/remover tool also called an apple corer, wrench, extraction tool, or BNC tool can be used to safely and effectively connect or disconnect BNC connectors in difficult-to-reach places.
Bayonet Neill Concelman BNC connector Advantages and Disadvantages
Advantages:
- Secure locking allows for quick connection and disconnect.
- Small and light in weight.
- Dependable medium-frequency performance.
- Available for several signal types in both 50Ω and 75Ω.
Disadvantages:
- Not appropriate for applications requiring frequencies higher than a few GHz.
- Less resilience to severe outside conditions in contrast to larger connectors (e.g., N-type).
Similar and Related Connectors
TNC (Threaded Neill-Concelman) Connector: The electrical properties and inventors of the threaded BNC connector are identical. It is more vibration-resistant and performs better at microwave frequencies (up to 11 GHz or higher) than the BNC’s bayonet lock because it has a screw-on threaded mechanism.
Twin BNC (Twinax) Connectors: Similar to standard BNC connectors, these have the same bayonet latching shell, but they have two separate contact points for joining a shielded differential pair (such as 78 or 95 ohm). They can only function at 100 MHz and 100 volts, and they are incompatible with conventional BNC connectors.
Triaxial (Triax) Connectors: In sensitive electronic measuring systems, a BNC variation that contains a signal, guard, and ground conductor is utilized. They frequently have three lugs to avoid unintentionally mating with regular BNCs.
High-Voltage Connectors (MHV and SHV): Utilized when the voltage exceeds 500 V. Although MHV connectors are sometimes confused with BNCs, SHV connectors were created as a safer substitute that avoids mating with regular BNCs.
Miniature Connectors: For HD video applications, Amphenol produces smaller versions such as Mini BNC and High Density BNC (HD BNC), which maintain electrical properties while providing a higher packing density. In certain applications, BNCs are also being replaced by other tiny connectors, such as DIN 1.0/2.3 and LEMO 00, for higher density.
Reverse-Polarity BNC (RP-BNC): In order to prevent them from mating with conventional BNC connectors, this variant has the contacts’ genders switched inside the connector.
