Currently available in two-position models (with six- and 10-position models under development), the series is rated for: 30VAC/DC, up to 3A per pin for power contacts and 0.3A per pin for signal contacts, 30mΩ maximum power contact resistance, 100mΩ maximum signal contact resistance, 1000MΩ minimum insulation resistance, and operating temperatures spanning -40ºC to +85ºC.
Smiths Interconnect’s ultraminiature NDLTriax connectors are offered in threaded (NDL-T) and quick-disconnect (NDL-Q) versions with straight and right-angle cable- and PCB-mount configurations, and both in-series and between-series adapters. Tested to MIL-STD-202 for corrosion, shock, vibration, and thermal shock performance, and rated for a minimum of 1,000 mating and unmating cycles, a maximum of 2A, and operating temperatures spanning -65ºC to +165ºC, the series is ideal for use in data-bus and video interconnect systems employed in space, medical, industrial, defense, commercial aviation, and alternative energy applications. The series’ cable-mount connectors are designed for numerous low-loss twinaxial cables and concentric triaxial cables available in a variety of impedance values and designed for all types of data-bus and video interconnect systems, including: MIL-STD-1553B, ARINC 429, 100Base-T, Ethernet, high-speed HOTLink, and Fibre Channel.
Cinch Connectivity Solutions’ Johnson line of UMC ultraminiature coaxial connectors and cable assemblies deliver high-quality, cost-effective, snap-on connections with DC to 6GHz performance, allowing engineers to achieve excellent price/performance ratios in a wide range of high-frequency applications, including: smartphones, GPS, wireless LANs, Bluetooth devices, electronic measuring instruments, and GPSs. The ultralow-profile cable plugs and jack receptacles offer maximum mated heights of 2.0mm and 2.5mm, feature gold-plated contacts and bodies, and mate with Hirose’s U.FL Series connectors. The full product line includes UMC, UMC to SMA, and UMC to UMC connectors, and R/A plug to R/A cable assemblies on 0.81mm, 1.13mm, 1.32mm, and 1.37mm cables. In-series UMC adapters are also available to support testing requirements.
Samtec’s LSEM, LSHM, and LSS Series high-density, high-speed Razor Beam™ ultraminiature interconnects feature rugged, but cost-effective blade-and-beam-style hermaphroditic interfaces that help reduce inventory costs and are available in a variety of pitches and lead styles for improved design flexibility. Options include: 0.5mm, 0.635mm, and 0.8mm pitch heights, 10 stack heights spanning 5–12mm, vertical and right angle orientations, up to 100 contacts, various lead styles, and optional shielding. The series also feature undercut retention notches that produce an audible click when mated and increase mating and unmating forces by approximately four to six times when compared to typical micro-pitch connectors. Additionally, LSHM Series connectors feature metal weld tabs that increase the mechanical strength of the part on the board and, for applications that demand even finer pitches, lower stack heights, and slimmer housings for additional PCB space savings, Razor Beam LP interconnects offer 0.4mm and 0.5mm pitches and stack heights down to 2mm.
ERNI’s miniature, dual-row, 0.8mm pitch MicroCon Series board-to-board connectors feature unique, double-sided female spring contacts and reinforced sidewalls that deliver robust, high-reliability performance and support up to 2.3A per contact and up to 3Gb/s data rates. The series also offers polarization and blind mate guidance to ensure secure mating alignments with ±0.7mm misalignment tolerance, and is available with up to 100 positions in right-angle (90°), coplanar, and parallel/mezzanine orientations with mated heights spanning 5–20mm.
