Würth Elektronik released the new REDFIT IDC SKEDD WR-WST solderless, reversible, direct-plug-in connectors for signal transmission, programming, and debugging in consumer and industrial electronics, solar, mechanical engineering, and switch board construction applications. Featuring 4–20 SKEDD-technology contacts that plug directly into plated through-holes on PCBs, the series enables quick, easy, and error-free mating over multiple cycles, affords both permanent and temporary connections, provides robust resistance against vibration, exhibits low contact resistance, and saves space, material, and process costs. The cable side also contributes to the connector’s high transmission quality via permanent, gas-tight IDC connections with flat, unstripped ribbon cable.
TE Connectivity’s new high-density (HD) card-edge power connector provides one of the highest current densities of any connector on the market. Designed to support 1,500–2,000W power supplies in next-generation server platforms and other data center equipment, the connector delivers 25A per contact, exhibits low contact resistance (averaging 0.4mΩ), low temperature rise, and low power loss, and has a 1.27mm signal contact pitch, a 5.08mm power contact pitch, and a 100V working voltage. It also has a compact, cost-effective design with a common PCB footprint, common power and signal contact module, and a maximum operating temperature of 130°C, offers flexible configurations with several different contact quantities and positions, delivers excellent mechanical and electrical performance, and enables easy mating and unmating and enhanced scalability.
Samtec’s new AcceleRate® HD is a 0.635mm-pitch, multi-row interconnect system that provides an ultra-high density interface and next-generation bandwidth. The ADM6 and ADF6 Series can have up to 240 total I/Os in a mere 1.88 square inches of PCB real estate with a low 5mm stack height (and with 7mm and 10mm options in active development). The system incorporates the Edge Rate® contact system, which is optimized for signal integrity performance, and is rated to 56Gb/s PAM4 modulation. Solder ball technology for simplified processing is standard, as are alignment pins and body polarization. The products are RoHS-compliant, lead-free solderable, and are also available as the slimmest cable assembly in the industry, with a 7.6mm body width ideal for closer proximity to ICs. The high-density, two-row cable assembly design offers 8- and 16-pair configurations on a 0.635mm pitch for up to 92 pairs per square inch and extends performance, reach, and system flexibility with Samtec’s flyover technology, which flies signals over lossy PCB via ultra-low-skew twinax Eye Speed® cable.
AVX Corporation’s new 00-9148 Series tall board-to-board stacker connectors are cost-effective, reliable, and robust; exhibit excellent resistance to shock and vibration; and help reduce tolerance accumulation in a variety of demanding applications across the automotive, consumer, medical, and industrial markets. The single-piece connectors also reduce assembly time and shorten BOM lists, and feature a double-row design with an 8mm (±0.2mm) board-stacking height, a 1mm pitch, and eight positions, each rated for 1A continuous current. Application-specific variants, including: single-row connectors with 4–16 positions, double-row connectors with 8–32 positions, connectors with 4–12mm board-stacking heights, and connectors with locating bosses for enhanced mechanical stability — all with the same fine 1mm contact pitch — can also be accommodated. Rated for 125V, 50 cycles, and temperatures spanning -40°C to +125°C, the series is ideal for connecting two parallel boards in applications including: automotive entertainment systems, portable devices that require docking or cradle charging, patient monitoring devices, portable medical equipment, industrial devices that require pluggable or programmable modules, and internet applications that require battery back-up.
