AMPHENOL PCD RJF21N Industrial Ethernet Receptacle

The RJF21N is a square flange receptacle with female RJ45 back termination designed for industrial Ethernet connections. It allows for reliable Cat5e Ethernet connections (10BaseT, 100BaseTX, 1000BaseT) in harsh environments, featuring the patented RJStop® system that protects the RJ45 connector inside a metallic plug from shocks, dust, and fluids. The connector includes a bayonet coupling with audible and visual signals, robust MIL-DTL-26482 H-size metallic shells, and a sealed IP68 design, making it resistant to shocks, vibrations, and pulling forces. It does not require field cabling or tools for installation and incorporates mechanical coding for polarization. Suitable for applications in robotics, industrial automation, process control, mining, oil and gas, and testing and measurement equipment.
