TE Connectivity CAT5 Industrial Mini I/O Field-Installable Connectors are compact (25% the size of conventional RJ45) wire-to-wire and wire-to-board solutions for reliable serial, bus, and Ethernet connections in industrial applications. These rugged connectors consist of only three parts (the termination unit, outer housing, and nut), allowing easy, quick, and error-free installation without the need for tools and wire length preparation. The CAT5 Industrial Mini I/O Field-Installable Connectors automatically cut off the wire at the optimal length during contacting, guaranteeing optimal (Cat5) transmission performance.
