The preLink® technology from HARTING is based on the idea of dividing a connector’s plug and socket into two robust and easily managed components. The first component being the plug or socket itself includes a variety of choices in several RJ45 and M12 variants. The second component is the termination block, which contains eight IDC contacts and is available to fit a wide range of wire diameters. Once the block is terminated to the wire, the block simply snaps into place and fits all variants of RJ45 and M12 plugs and jacks.
