       Single-port metal shielded gigabit RJ45 jack with 4.90mm flat through-hole pins, standard 8P8C gold-plated contacts, each port equipped with green & yellow dual LED indicator lights. Integrated full galvanized steel shielding shell with built-in gigabit isolation filter transformer supports 10/100/1000M adaptive transmission, blocks electromagnetic interference and static surge to protect main control chips. Flat pins expand soldering contact area for even tin adhesion, matched with side positioning buckles to prevent shifting and cold solder joints during PCB reflow, improving mass production yield. Solid green light indicates stable network link, flashing yellow light shows real-time data transceiving status. Widely used for gigabit switches, industrial gateways, industrial control boards, surveillance NVR and IoT communication equipment. 3600 pieces per export carton, stock lead time 2-3 working days. Custom non-LED, variable-length flat pin and SMD versions are available, direct supply from manufacturer with bulk customization supported.
