the HT803/IXG- 8/10S-63-72 cable assembly tool that can be used with
IX30G, IX31G, and IX32G IDC ix connectors (Figure 5). It’s a combined tool for crimping the cable and plug together and swaging the protective housing onto the assembly. In the case of IX40G soldered connectors, it’s only used for swaging.
This cable assembly tool is designed to work with shielded cables from 22 to 28 AWG with seven-stranded annealed copper wires with an outside insulation diameter from 6.3 to 7.2 mm. Operation is quick and simple. Crimping: Place the plug in the tool with the coding key facing up and insert the cable into the plug. Squeeze the handle to complete
the crimping. The tool includes a ratchet mechanism to ensure that it does not open until sufficient pressure has been applied to produce a good, crimped connection. The ratchet automatically releases when the required pressure has been achieved. Swaging: Place a shield shell and case into the tool (a special cutout is provided to ensure proper placement). As with
the crimping process, place the plug into the tool with the coding key facing up. Squeeze the handle until the ratchet releases to complete the
swaging. Testing is important
There can be several reasons for testing Ethernet cables in the field. During initial deployment of equipment or replacement of existing cabling, testing can certify that the

cable meets all performance requirements. Cable testing is also useful when troubleshooting installations to pinpoint the source of a problem. There can be numerous sources of failures in an Ethernet network, including failed connectors, cable or shield breaks, and increased susceptibility to EMI. The DSX-CHA-5-IX-S from Hirose is a set of two adapters optimised to speed field testing of ix connectors and cable assemblies (Figure 6). It’s designed for use with DSX CableAnalyzer testers from Fluke Networks. Thorough testing to IEEE 802.3 specifications using these adapters can provide pass/fail results, along with extensive diagnostics to speed the identification of any problems.
Digital options for connector configuration D
esigners face a large range of options when creating interfaces for their product. Whether for electrical signal, power, fibre optics, an alternative medium or a combination of all, the choices are almost limitless. So, the main challenge for the connector supplier is to offer the OEM a simple methodology to find the ideal solution. The classic way is to provide engineering support for in-depth design-in discussions. Understanding the requirements in detail and creating the ideal solution
together is the best building block for a long- lasting business partnership. However, some customers prefer to navigate their own way through the product offerings and expect easy access to technical data. While print and online catalogues remain important as a complete compendium, search engines offer not only detailed product specifications for direct comparison, but also a selection of 3D files for easy integration into the client’s own designs. ODU offers both methods of
design-in support and is also highly integrated into many external online platforms.
However, ODU’s own website offers the Product Finder at https://
odu-connectors.com/uk/find-your- product/. This intuitive, easy-to-use system finds the optimal connector or cable-assembly and creates a data sheet. Another advantage of the Product Finder is the identification of those products available via the ODU Express Delivery Service.
Within 15 working days, up to 15 modular connectors or 150 metal circular connectors can be shipped worldwide.
www.odu-uk.co.uk Harwin showcases industrial connectors at embedded world A
dvanced interconnect specialist Harwin will be using the upcoming embedded world event (Nuremberg, 14-16 March) to focus on its newly defined BBi product portfolio. These high density board-to-board connectors are intended for use in challenging industrial applications, providing assured long-term operation. The BBi portfolio includes components for drives and controls, edge-based computing hardware, automation systems, robotics, instrumentation and monitoring equipment, IIoT infrastructure, smart meters, etc.
36 February 2023 Among the different options available are:
● The 0.8mm-pitch Archer .8 series connectors - These low-profile double-row format units are well suited to mezzanine motherboard/ daughtercard usage. They support the 24Gbps data rates needed by the latest generation of industrial networks. ● The Archer .5 series of 0.5mm-pitch connectors - Available in 30, 40, 80 and 100 pin count versions, these ultra-compact components mean that even the most space- constrained scenarios can be addressed. Their

www.cieonline.co.uk Conclusion
Designers can use ix connectors to support the need in Industry 4.0 systems for high density, robust connectivity. These connectors are available in Ethernet and non-Ethernet configurations, with various mechanical configurations available to support a range of system design needs. Solder connections can be used in high-volume production settings, while IDC models are available for making cable assemblies in the field. Tools and testers are also readily available to ensure that the resulting cable assemblies meet all the ix performance requirements.
