Ethernet cabling system for all device connectivity needs


General DPN

Harting Canada has introduced Ha-VIS preLink, an Ethernet cabling system for a broad range of industrial applications.

It is based on the simplicity of a termination block the user wires separately, then snaps securely into any one of seven mating profiles: RJ45, PushPull RJ45, M12 D-coded, M12 X-coded, RJ45 Harting Industrial Form Factor, RJ45 Keystone and a preLink extender for cable extensions and transitions, solid-stranded.

Cabling with Ha-VIS preLink is said to be extremely fast and simple, a single operation whatever the intended mating profile. Wires are inserted into the preLink termination block according to their color codes. A special preLink® crimping tool ensures the wires are always assembled precisely and correctly. The cable is terminated and extra wire trimmed in one step. When the wired termination block is snapped into place in the connector, it becomes an integral part of that unit, not a separate interface.

Harting’s preLink system is particularly well suited for installations in cramped spaces or junction boxes. Pre-assembled cable segments can be swapped out quickly during maintenance and upgrades. It also offers users a unique opportunity for future-proofing: An eight wire cable can be terminated even for use in a four-wire format.

When the time comes to upgrade, like switching from fast to Gigabit Ethernet, there is no need to re-terminate: The wired termination block can be moved from a 4-pole D-coded M12 to an 8-pole X-coded M12 housing in seconds. Until that day comes, the unused pairs are shielded to prevent cross-talk.
