RNJ - Reduced Flange

The Amphenol Socapex RNJ Blind Mate connector offers up to 20% weight savings compared to standard RNJ plugs. Designed for rack-to-panel connections without manual coupling or uncoupling, the RNJ uses the same contacts and inserts as MIL-DTL-38999 Series I & III and is compatible with many M85049 backshells. A reduced flange (double flange) receptacle version is also available for additional integration flexibility. With more than 80 contact arrangements from size 23HD to size 4, the RNJ supports signal, power, high-speed (Coax, Twinax, Quadrax, Octomax), and optical termini, with crimp and PC-tail terminations offered in gold or tinned versions. Built from robust materials with multiple plating options (Olive Drab Cadmium, Black Zinc Nickel, Nickel), the connector withstands 500 mating cycles, operates from -65°C to +175°C, and achieves IPX7 sealing when mated and fully cabled. Electrical performance includes insulation resistance of 5000 MΩ at ambient and current ratings from 3A to 100A, making the RNJ ideal for high-density, high-reliability interconnects in C5ISR, ground vehicles, avionics, commercial aerospace, missiles, and space applications.

What are the main benefits of the RNJ?

The RNJ connectors ensures floatability and realignment while offering blind mate possibilities. The connector's design helps the good mating while guiding the plug into the receptacle and adjusting if needed, following its realignment tolerances on 3 axis : 1mm on axial axis; 6° on angular axis and 0,5mm on longitudinal.  To learn more about Rack and Panel RNJ connectors.

What materials and plating are available?

RNJ and RNJ LP connectors are available in Aluminum with Olive Drab Cadmium, Black Zinc Nickel and Nickel plate, and in Stainless steel too (303 or 316L).

What is RNJ LP?

The RNJ LP is a RNJ Low profile, meaning the distance between the 2 panels have been reducing at maximum, while providing the same benefits than a standard RNJ. It is available with all 38999 series III layouts and similar materials than the RNJ. Find out more information in the catalogue at the top of the page.
