General
Socket diameter	4 mm
Spacing between sockets	19 mm

The BNC plug with safety sockets from Chauvin Arnoux is a specific test accessory for secure and precise connection of test instruments and cables in electrical applications. The device features two insulated sockets in red and black, each with a diameter of 4 mm and a standardized spacing of 19 mm between them. This design enables clear polarity assignment and reliable mechanical connection with compatible test cables and connectors. The sockets are designed for use in demanding environments and comply with the safety standard 600 V CAT III, ensuring high electrical insulation and protection against overvoltages. Thus, use in laboratories, workshops, or technical facilities is safe and compliant with standards.

Applications

The BNC plug is primarily designed for electrical measurements, especially in environments with high safety requirements. The safety class CAT III 600 V makes it suitable for measurements on installed electrical systems, for example in industrial or commercial operations. The color coding of the sockets (red/black) supports correct polarity when connecting to test instruments such as oscilloscopes or multimeters. The robust construction and socket insulation protect the user and the device from electrical hazards.

Functions and Equipment in Detail

The two safety sockets have a diameter of 4 mm and provide a secure mechanical connection for standard test cables. The 19 mm spacing between the sockets corresponds to a common standard in test technology, ensuring simple and unambiguous connection options. The colors red and black are used to distinguish polarity, minimizing wiring errors. The sockets are insulated to prevent short circuits and electrical hazards.

Technology Explained Simply

The BNC plug is a bayonet connector commonly used at test inputs of oscilloscopes and other test instruments. The term BNC stands for Bayonet Nut Connector, a plug system that enables a secure and quick connection via a twist-and-push locking mechanism. The integrated safety sockets with a 4 mm diameter are designed for connection with standard test cables. The socket insulation and safety class CAT III 600 V ensure that the plug operates safely even at high voltages. The CAT III 600 V standard is intended for measurements on installed electrical systems that may carry up to 600 volts under normal operating conditions.

Compatibility and Accessories

The BNC plug is compatible with test instruments featuring BNC connectors, particularly oscilloscopes and multimeters. The 4 mm sockets allow connection with standard test cables equipped with 4 mm banana plugs. The color coding (red/black) supports correct polarity assignment. The accessories are part of a comprehensive range of BNC adapters and cables from Chauvin Arnoux, developed for use in laboratories and on-site.

Installation and Mounting

Installation is performed by simply inserting the test cables into the safety sockets and then locking the BNC plug onto the test instrument. The sockets are already integrated into the plug, so no additional mounting work is required. The connection is mechanically stable and can be made without tools. The socket insulation and safety standard CAT III 600 V ensure that the connection remains safe even under load.

Operational Advantages

Using the BNC plug with safety sockets provides high safety when measuring electrical quantities. The socket insulation and CAT III 600 V standard protect the user and the device from electrical hazards. The color coding and standardized 19 mm spacing facilitate correct and quick connections. The robust construction ensures long service life and reliable performance in various operating environments.
