General
Impedance	50 Ohm
Maximum current	3 A

The BNC connection accessory from Chauvin Arnoux serves as a connecting element between measuring instruments and accessories in laboratory and technical environments. It is a cable with male/male connection, having a length of 1 m, specifically designed for signal transmission with an impedance of 50 Ohm. This impedance is crucial for optimal signal transmission, as it minimizes reflections and distortions, which is particularly important for high-frequency measurements. The cable is designed for demanding applications and complies with the safety requirements of categories 600 V CAT III and 1000 V CAT II according to the standard IEC 61010-2-031. These standards define the electrical safety for measuring and testing equipment and their accessories, where CAT III applies to installations connected to the power grid during operation, and CAT II applies to installations with lower risk. The maximum current rating is 3 A, enabling its use in a wide range of measurement tasks without exceeding the electrical load capacity.

Applications

The cable is particularly suitable for use in laboratory environments and technical installations where safe and reliable signal transmission is required. It is frequently used for connecting oscilloscopes, signal generators, network analysers, and other measuring instruments equipped with BNC connectors. The category 600 V CAT III also makes it suitable for measurements on installations connected to the power grid, where the use of an insulated cable complying with at least CAT III is mandatory to ensure operator safety.

Functions and Equipment in Detail

The BNC connection accessory features a male/male connection, enabling a direct connection between two BNC plugs. The length of 1 m provides sufficient flexibility for use in various working environments without compromising signal quality due to excessive cable length. The impedance of 50 Ohm is a standard value in high-frequency technology and ensures consistent signal transmission without phase shifts or attenuation. The maximum current rating of 3 A ensures safe use in measurements requiring higher current, without overloading the cable.

Technology Explained Simply

The impedance of 50 Ohm is a critical parameter for signal transmission. It ensures that the signal is transmitted without reflections at the end of the line, which is especially important for high-frequency signals. The safety classes 600 V CAT III and 1000 V CAT II refer to electrical insulation and the maximum permissible voltage that the cable can safely transmit. CAT III applies to installations directly connected to the public power grid, while CAT II is intended for installations with lower risk. The standard IEC 61010-2-031 sets the requirements for the safety of measuring and testing equipment and their accessories.

Compatibility and Accessories

The cable is compatible with all devices equipped with BNC connectors, particularly measuring instruments such as oscilloscopes, signal generators, and network analysers. It can be used as a replacement or additional cable for existing measurement systems. Its use in combination with other BNC connection elements allows flexible adaptation to different measurement tasks.

Installation and Mounting

Installation is performed by simply plugging the BNC connectors into the corresponding sockets on the measuring instruments. No additional tools or mounting procedures are required. The connection is mechanically stable and ensures a reliable electrical connection.

Operational Advantages

The combination of high impedance accuracy, electrical safety, and mechanical stability makes the cable a reliable component of measurement systems. Compliance with the standard IEC 61010-2-031 and the safety classes CAT III and CAT II ensures safe operation even in demanding environments. The length of 1 m provides sufficient flexibility without impairing signal quality.

Scope of Delivery

The product is delivered with a BNC connection cable (male/male, 1 m length) and documentation.
