AMPHENOL PCD RJF21G Ethernet Connector

The RJF21G is a female RJ45 Ethernet connector designed for harsh environments. It supports Ethernet Class D/CAT5e connections for 10Base-T, 100Base-TX, or 1000Base-T networks. The metallic plug features a quick, secure 1/4 turn bayonet coupling mechanism (MIL-C-26482 type) with audible and visual confirmation of attachment. The connector has a square flange receptacle shell made of olive drab cadmium-plated aluminum with metalized inserts, offering sealing against fluids and dust contamination. It is resistant to shock, vibration, and traction, requiring no tools or cabling operations during installation. The design provides enhanced electromagnetic interference (EMI) protection and is rated for a minimum of 500 mating cycles. Operating temperature ranges from -40°C to +85°C. Suitable for use in communication, networking, and system monitoring applications.
