I-PEX ConnectorsWire-to-board connector products: I-PEX Connectors offers a wide range of micro-coaxial connectors and cable assemblies offers a wide range of micro-coaxial connectors and cable assemblies designed to provide high-data-rate signal transfer over long distances. Solutions support transfer speeds up to 100Gb/s (25Gb/s per line) and offer compatibility with standards including USB 3.1 Gen 2, PCIe 2.0, 3.0, and 4.0, eDP HBR2 and 3, SATA 3.0, HDMI 2.0, Thunderbolt 1, 2, and 3, and IEEE 100GbE. Cables in the micro-coaxial product portfolio have center conductors, dielectric cores, and outer conductors that are suitable for matching, stabilized at a specific impedance to achieve low return loss, and shielded to help reduce external noise and/or crosstalk between signal lines. Connectors in the micro-coaxial product portfolio are available in horizontal, right-angle, and vertical mating configurations with 0.25mm, 0.3mm, 0.4mm, and 0.5mm pitches, have a metal EMI shield that goes over the entire connector to provide interference protection, which grows ever more critical as data rates climb, and have locking mechanisms to ensure secured connections and prevent accidental disconnection. To create complete harness assemblies, users simply align prepped cables (i.e., cable sub-assemblies) to the plug housing, solder the center conductor of the cable to the plug contact, place the lock, and solder the ground bar and shell. Since the ground bar is conducted with all cable outer conductors, it is possible to conduct the entire connector system (i.e., both the plug and receptacle) and achieve good grounding characteristics by simply soldering several points between the ground bar and shell. Micro-coaxial cable assemblies can be made with different cable diameters, can address both signal transfer and power supply needs with a blend of micro-coaxial cables and discrete cables, and can include ground fingers/tabs on the ground bar for direct plug attachments. These flexible assemblies are ideal for use in space-constrained electronics devices including notebook PCs, moving cameras on drones, and other equipment that incorporates Wi-Fi, GPS, and LTE capabilities.
