RNJLP - Rack & Panel Low profile description

The Amphenol Socapex RNJLP Rack & Panel Low Profile connector is a lightweight, high-density solution for harsh environments. Derived from the 38999 series III, it features realignment capability on three axes, allowing for axial, angular, and longitudinal realignments. The RNJLP offers the same panel distance as the ARINC 404 and is suitable for applications such as battlefield communication, military avionics, and grounded vehicles. The RNJLP connector boasts EMI shielding and grounding fingers that ensure shielding before contact mating. It has a large contacts range, including M39029 contacts compatible with Mil-DTL-38999 III 22D, 20, 16, 12, 8, and 4 contact cavities for signal, coaxial, twinax, and power contacts. The connector has a wide range of shell sizes, ranging from 11 to 25, and is made of a lightweight aluminum alloy. The plug version of the RNJLP offers a 20% weight savings compared to the standard RNJ version. It features a reinforced membrane on the floating plug, ensuring high pressure resistance and a 100% scoop-proof design for contact protection. The RNJLP is fully compatible with all M-85049 backshells for Mil-DTL-38999 series III, making it an excellent choice for applications that require realignment and floatability in harsh environments.
