Modular/Ethernet Connectors

L-Com Modular/Ethernet Connectors are designed to meet the demands of standard commercial networks and rugged industrial environments. These connectors offer high-performance data transmission, modular designs, robust housing options, compliance with industry standards, and tool-less or quick-connect options. The modular/Ethernet connector types are RJ45, RJ11, RJ12, industrial/ruggedized RJ45, M12, and M8 connectors. These connectors are ideal for voice, video, data, LAN setups, industrial automation, outdoor and harsh environments, and custom networking installations.
