A new reflow-capable RJ45 jack is available in the industrial Y-Con® RJ45 series. The socket for 100 Mbit/s basically consists of a base body with 90° orientation of the connector to the solder pins, along with the “Tab-up” tab orientation. The individual types vary in features to ensure that the right product can be selected to meet customer needs.
The jack optionally has machine-wound transformers, additional integrated power contacts and reflow-capable light pipes. For the power contacts and reflow-capable light pipes, Yamaichi Electronics relies on a mature design that provides customers the greatest possible flexibility in the transmission of power up to 100 W as well as in the transmission of optical signals.
With the two additional power contacts, up to 2.1 A can be transmitted at 70 °C without affecting signal transmission. This is significantly more than provided by PoE. It also saves another cable.
When using light pipes, on the other hand, optical signals can be transmitted from the PCB on the front of the jack just as with an optical fibre. In contrast with the LEDs, however, light pipes have a nearly unlimited lifetime and a cost advantage. The use of light pipes in reflow soldering is also not limited by the high solder temperature, and there is still complete freedom in the selection of light colour.
The integrated machine-wound transformers ensure optimum, consistently good signal transmission, for example if there is no space on the PCB for magnetics when using Ethernet. In contrast with hand-wound transformers, in which performance can depend on the capability of the maker, machine-wound transforms ensure consistent transmission quality. They are also insensitive to vibrations, since the coil bodies are always cast. The series can therefore meet the strictest of requirements in the industrial sector.
Yamaichi Electronics has extended its MXM family for automotive and other demanding applications with a 314-pin variant. The success story for the board edge connector (BEC) developed and tested specifically for automotive applications began about six years ago: the BECs were the first connectors for modules meeting the MXM and Qseven standards with 230 pins and a 0.5mm pitch. In 2013 a 230-pin high-speed version of the BEC for applications to 5 Gbps was premiered.
To meet the requirements of MXM3.0, Yamaichi now offers a 314-pin variant alongside the 230-pin high-speed version. Applications with an increased need for high-speed signal contacts are thus also accommodated.
Yamaichi draws on a proven design for this. For example, the contacts have the characteristics needed to ensure a stable contact force even when subject to vibrations and shock. The spring characteristic of the contacts also permits tolerance compensation and reliable data transmission if modules with dimensions close to the tolerance limits are used.
A new feature is the extended function of the module’s side screw fitting. The tabs on the screw fitting can be folded out to facilitate insertion of the PCB. Following module assembly the tabs are returned to their original positions and screwed from above to the module and the connector. Thus the module is securely fastened to withstand vibrations and shock.
The enlarged SMT tabs are used for the ground connection and for the SMT connection – along with the 314 contacts – to the motherboard.
Yamaichi has thus managed to combine 314 high-speed contacts and robustness in a single system.
The connector is currently available with a 0.1µm-thick gold plating in the contact area. It is packaged and delivered in T&R. Production is nearly exclusively automated.Læs mere
Yamaichi Electronics has launched a new 0.5 mm pitch high-speed transmission FPC connector for several markets such as industry, automotive, and data networking. The main features include the ability to transmit up to 20 Gbps, the very compact design and the direct locking feature for the FPC.
The first advantage is the high-speed ability. Using Yamaichi Electronics´ original FPC called YFLEX® the system is able to transmit up to 20 Gbps.
With standard FPCs the connector can transmit only up to 10 Gbps. Depending on customer requirements, the internal connection can be provided as a whole package consisting of cable and connector. Impedance is matched to 100 ohm. Therefore, it offers an added advantage for use in high frequency environments such as LVDS, TMDS, V-by-One HS or FDP Link.
Once the current maximum speed is achieved, this connector can send signals according to the IEE 802.3bj specification for 28 Gbps per channel required in the data networking market. Yamaichi Electronics is now investigating for methods to achieve 56 Gbps standardized with CEI-56GVSR&MR for the next generation.
Secondly, this connector is one of the smallest designs in the market and saves space for other layouts on the PCB. It is available with 30, 40, and 50 pins. Even the version with a maximum pin count of 50 has a length of only 33.5 mm. The width is only 4.9 mm. The contact pitch is 0.5 mm.
Third, the system is very easy to assemble. There is no need to attach an adapter to the cable side. Thus the cable can be plugged directly into the connector. Once the connector is unplugged, the operator only needs to push a metal part located in the middle of the connector to pull out the cable.
The HF513 connector is suitable for internal connections which require high-speed data transmission in a very dense area. Moreover, with its easy operation mechanism it saves handling time in the production process.
