RK 40-839/20M

Circular Cable Assemblies are naturally suitable for connecting multiple units where cables need to be coiled, twisted, or bent around the connector. This allows the user to route the cable to a secure, safe location with greater ease. Specifically, the type of utilisation these assemblies lend themselves to, are applications in the defense and aerospace industry, power and data cables in automotive sectors, control panels, construction equipment, material handling systems and connecting networking equipment at data centers, which require a secure connection with greater flexibility. The RK 40-839/20M type of Circular Cable Assembly comprises of two parts: the connector plug and the receptacle backshell. Connectors and backshells are more often than not differentiated by the type of cable they are used with, as the type of cable and its protective covering can vary greatly. Technical information can be found in the catalogues of manufacturers, or alternatively by speaking to a member of the technical sales team at a distributor. The principle of the Circular Cable Assembly is relatively simple, with the two ends of the cable being connected by forming a secure and reliable connection. Connector plugs have contacts embedded at their tip, which make contact with the cable’s core to complete the electrical circuits in the cable. The connector plugs are mechanically and electrically matched to the backshell in order to provide a secure and stable connection. As the assembly is specifically designed to meet industry-standard requirements, the number of contact sockets and other related features will depend on the specific application. In terms of the connector itself, the contacts are usually gold plated and protected against corrosion and contact burnout. The RK 40-839/20M is a high grade circular cable assembly, with a number of features that make it suitable for tough environments. It has a current carrying capacity of up to 20A/Per Pin with a voltage range of 750V. The connector is UL listed and can be used with temperatures ranging from -55C to +125C. The IP67 rating also makes it suitable for damp environments. The plug is also protected against EMC/ EMS interferences with a maximum EMC attenuation of -80dB. Measured in dB, this figure is the amount of power absorbed by the connector when transmitted through a steady-state signal, providing accurate sound and true picture. The RK 40-839/20M is also a suitable connector for burst transmission applications with its low mating case duration of less than 5 ms. In conclusion, the Circular Cable Assembly family, and specifically RK 40-839/20M is designed to provide secure, reliable and high performance connection of cables in applications as varied as defense and aerospace, automotive, control panels, construction equipment, material handling systems and data centers.
