HARTING RJ Industrial® 4 pair
The HARTING RJ Industrial® Gigalink more than meets the tough requirements of Category 6 according to TIA/EIA 568 B.2-1:2002-06, EN 50173-1:2002 and ISO/IEC 11801:2002-09.
The integrated cable management system with simultaneous wiring radically reduces installation times in comparison with existing systems. The cable manager, which can be colour-coded, supports the simultaneous insertion of the cable strands, so avoiding the time-consuming manual placement of the individual conductors.
The RJ Industrial includes an integrated cable adjustment system, such that a high quality connection is maintained in tough industrial environments over long periods, even under conditions of heavy vibration. This ensures that the shielded twisted cores are reliably guided to their contacts within the connector. Without this innovation it would be possible for the shielding braid of the individual conductors to separate, resulting in a long-term deterioration in the crosstalk characteristic of the connector and therefore of the entire transmission line. The HARTING RJ Industrial® also exceeds the clearance and creepage requirements for industrial environments.
Connector family
Because of the innovative platform strategy implemented in the RJ Industrial Gigalink data module, all the other products in the RJ Industrial product family can also be used for Gigabit Ethernet.
This makes Gigabit Ethernet with Real CAT 6 also possible with IP 67 protection.
The used CAT 6 data module adapter
fits into the shielding plates of the 4 core data module with quick-connection
technology. For this reason an existing 100 Mbit Fast Ethernet transmission
line with HARTING RJ Industrial® connectors can easily be converted into
a Gigabit Ethernet transmission line, without having to modify the connector's
interface. This makes the HARTING RJ Industrial® connector family as future-proof
as possible.
Minimising cross-connection through cable management
There is no difference under Gigabit Ethernet between uplink and downlink ports. Every network device automatically recognises whether the device to which it is connected is a network card or a switch. There is therefore no need for cross-connected and throughconnected cables found under 100 Mbit Fast Ethernet, where this functionality is not available.
The symmetrical structure of a 1:1 through-wired patch cable results in cross-connection of core pairs 2 and 4 in the cable. This cross-connection has a negative effect on the near-end crosstalk of the transmission route. For performance reasons, symmetrically crossing the core pairs in the cable must be carried out as near as possible to the connector. This demand is implemented through the colour-coded cable manager, which leads the conductor pairs in a defined way to the connection points on the RJ 45 jack. This implements the cross-connection in the cable manager instead of in the cable itself, so contributing to the high performance of the transmission route.
Connection of core pairs
Wiring the data module
For historical reasons, TIA/EIA 568:2002 has two ways to connect the conductors at the connector. These describe which individual colour-coded conductors are to be brought to which contact in the connector.
TIA/EIA 568:2002 A is the most common connection variant. This configuration is also described in ISO IEC 11801.
The TIA/EIA 568:2002 B connection variant is primarily used for the connection of ISDN networks (AT&T configuration).

Connection in acc. with TIA/EIA 568B (AT&T configuration)
The RJ 45 jack must be connected according to the appropriate scheme, depending on the application. For Gigabit Ethernet the connection is only to be made at the RJ 45 jack, not at the plug, since the conductor pairs in the patch leads are symmetrically routed due to the 1:1 auto-crossing.
