As the core conductive components of the JRKCONNC series, contact elements (including pin and socket contacts) form the electrical transmission interface of circular connectors, establishing stable electrical signal pathways between mated interfaces. To ensure consistent performance under rated electrical parameters, complex operating conditions, and mechanical stress, the design and material selection of contacts are critical.
High-quality contact elements should form low-resistance, highly reliable electrical connections between matched contact bodies. JRKCONNC recommends using consistent contact body materials on mating terminals to maintain electrical characteristic stability and reduce the risk of electrochemical corrosion. If not properly interconnected and mechanically protected through compatible housing structures, the probability of early system failure increases significantly.
To meet diverse application requirements, JRKCONNC offers a wide range of contact solutions, covering variations in base metal materials, structural dimensions, mating lengths, contact area ratings, and other key parameters. These contact elements are currently widely used in circular connectors across fields, including military applications with high-reliability demands, corrosive offshore environments, commercial equipment, and harsh industrial operating conditions.
