The new feed-throughs are available for circular and square panel cut-outs for integration into industrial devices and switch cabinets.
A key feature is their significantly improved electromagnetic compatibility. The category 6 performance of the RJ45 female module offers system reserves that are high enough to carry not only standard Industrial Ethernet but also 1/10 Gigabit Ethernet signals.
The RJ45 socket inserts have a 360° shield to increase electromagnetic compatibility and ensure interference immunity for the transmission path. Even at burst interference levels greater than 4 kV, stable and secure industrial Ethernet transmission is guaranteed. The flexible grounding concept also provides users with a greater number of options.
The feed-throughs allow rapid and easy fitting into devices and switch cabinets as well as retrofitting existing housings with a PROFINET interface to protection type IP 65/67. Users can choose from two RJ45 inserts. The RJ45 female model RJ Industrial(R) Bulkhead Cat.6 (with two RJ45 connectors) makes it possible to route the Ethernet signal inside the device or switch cabinet with simple IP 20 patch cables. The RJ45 cable socket Ha-VIS preLink(R) (with one RJ45 connector and eight IDC connections) allows easy and rapid build – pre-assembled or on site in the field – with an insulation displacement connection for connecting data cables to AWG 22/7 – AWG 23/1 cross sections.
Electromagnetic compatibility – and particularly protection against bursts – is critical in terms of the interference immunity of field devices in automation environments. Bursts consist of low-energy but transient interference that can couple capacitively with Ethernet data signals in applications such as welding equipment, and can compromises reliable communication with affected bus slaves.
To enable users to decide on the grounding concept for their equipment, RJ45 female connectors lock into the metal panel feed-through, making it potential free and therefore electrically insulated. This ensures that the RJ45 shield potential and the chassis ground are not connected by accident.
Users wishing to ground the RJ45 shield potential can clamp it to the metal panel feed-through or the RJ45 female connector via a blade connector. This effectively diverts electromagnetic interference coupling to the data shield and prevents it from entering the device.
