New installation concept for data network cabling

11 April 2011

Harting’s Ha-VIS preLink, a new installation concept for data network cabling based on the ISO/IEC 11801 standard, saves installation time and enables extensions and conversions to be made without incurring significant interruptions to operations. It is suitable for use with a wide range of mating faces such as RJ45 (to IP20), RJ45 PushPull (to IP65/67) or M12, opening up a wealth of opportunities and potential for users. Ha-VIS preLink also includes components for 10Gbit Ethernet transmission rates.

The new product is the latest addition to Harting's Automation IT concept, which provides a seamless Ethernet-based communications platform for integrating office IT systems with industrial automation to optimise manufacturing workflow efficiency. It supports a standardised cabling installation in which the Class EA link is created before the mating face is chosen. The technology supports connectors that are specified for structured industrial building cabling, as well as connectors for automation profiles, with users benefiting from the flexibility to mix and match the mating faces and housings.

The new system combines Harting’s pre-fabricated preLink cabling links with its preLink connectors. The data cable, with cable terminals crimped on at both ends, forms the preLink cable link that is the functional backbone of the cabling system. The cable terminals, which dress the ends of the cable and act like end ferrules, are compact and cause only a minimal increase in cable diameter.

As Ha-VIS preLink ensures both the electrical and the HF performance of the preLink connection, the pre-terminated cable can be combined with any mating face for maximum flexibility and ease of use. The preLink connector simply snaps on to the preLink cable terminal, and the complete unit forms an ISO/IEC 11801 (EN 50173) compliant permanent link or an end-to-end link that complies with Profinet automation profiles.
