R-Jack® Industrial RJ45 Solution

Installation zone RECOMMENDATION

The R-JACK® Ethernet Connector provides an efficient, comprehensive and affordable solution for Ethernet connectivity in harsh and environmentally challenging applications. Unlike low quality plastic RJ45 receptacles, R-JACK is designed to ensure guaranteed performance and durability even in the harshest conditions. In addition, R-JACK provides a variety of options, including pre-kitted solutions that are designed to integrate seamlessly with industrial and hardened environment applications.


  • 10/100/1000BASE-T Ethernet
  • POE, POE+, and POE++
  • DATA, VOiP, and IPTV in Harsh Environments
  • Radar Systems
  • Industrial Process Control
  • Mobile Equipment Transit Cases
  • Data Acquisition and Control
  • Shelters
  • Battlefield Communication Systems


  • Compact design that delivers optimum protection. R-JACK jam nut (ECRK) and flange mount (ECRD) type receptacles provide higher panel density than current MIL-DTL-38999 style products. For customers wanting to upgrade to R-JACK, a MIL-DTL-38999/24 shell size 19 style jam nut receptacle (ECRJ) is available to fit existing panel cutouts. A common cable strain relief for plugs and receptacles accommodates both small and large cable diameters, complete with compressive fittings for shielded cable. R-JACK receptacles offer a 100% transversely sealed (IP-68) configuration option, preventing dust, water or moisture penetration, with or without dust cap or plug engagement.
  • Designed for integration. R-JACK is designed to work with jam nut, flange mount, in-line receptacle and plug options. OCC also offers completed R-JACK harness assemblies for drop-in-place applications. Pre-kitted solutions, including gaskets, O-rings, mounting brackets, and hardware, make it easier for customers to procure, install and integrate these components.
  • Comprehensive shielding performance. R-JACK plugs, receptacles, and backshells are designed to establish grounding between shielded cord sets, as well as between cord set and chassis ground. When immunity to electromagnetic interference is critical, the R-JACK's EMC/EMI shielding capabilities also provide exceptional protection.
