AMPHENOL PCD RJF54421 Rugged Ethernet Connector

The RJF54421 Ethernet connection system features a square flange receptacle shell with female RJ45 back termination, supporting Cat 5e networking for 10BASE-T, 100BASE-TX, and 1000BASE-T in rugged environments. It utilizes the patented RJStop system, enabling the use of standard RJ45 cords within a protective composite plug that shields against shocks, dust, and fluids. Designed for harsh industrial settings, it offers IP68 sealing, quick push-pull coupling, and 100N retention. Its EMI protection and compliance with IEC standards make it ideal for automation, robotics, process control, and communication networking applications.
