Connectors for Test & Measurement

The N Series of mini modular, high density connectors from Smiths Interconnect Automotive testing equipment must be highly sophisticated and sensitive, and at the same time, exceptionally robust so that it can keep putting the vehicles and components through their paces. The N Series of mini modular, high density connectors from Smiths Interconnect offers a variety of combinations in a single connector frame. It employs a do-it-yourself system based on the building block principle, which allows users to select the connector design that meets their specific requirements through off-the-shelf components. Based on patented Hypertac Hyperboloid “basket of wires” innovation, these interconnects offer very high mating cycles combined with low insertion and extraction forces for greater durability, as well as an unparalleled immunity to shock and vibration.

The new Cardinal line of high-performance cable assemblies from MolexThe new Cardinal line of high-performance cable assemblies from Molex are high frequency products with performance up to 110 GHz. They feature ruggedized armored VNA test cables along with standard flex cables that are ideal for bench top testing. Connector options include SMA, 3.5mm, 2.92mm, 2.4mm, 1.85mm and 1.0mm series. In addition to the cable assemblies, the new high frequency products include precision in-series and between-series adapters as well as the new line of End Launch PCB connectors.

Amphenol Communications Solutions’ ultra-high mating cycle DDR5 connectorsAmphenol Communications Solutions’ ultra-high mating cycle DDR5 connectors for DDR module and chipset test equipment feature ultra-high mating cycles. These 287-terminal DDR5 connectors are ideal for applications requiring extremely high mating and unmating cycles of up to 100,000 connections. The solderless process allows the connector to be replaced with minimal damage to the PCB, thus avoiding equipment downtime. Amphenol’s ultra-high mating cycle DDR5 connectors also comply with the new interface standard JEDEC SO-023D and JEDEC SO-023. Both RDIMM and UDIMM versions of this DDR5 socket are tooled and available.

The extremely low 3.8 mm profile allows the Samtec Si-Fly™ Flyover Cable SystemThe extremely low 3.8 mm profile allows the Samtec Si-Fly™ Flyover Cable System to be placed adjacent to the IC package and under heat sinks or other cooling hardware for design flexibility. Si-Fly and other Samtec Flyover Cable solutions are designed to get signals off the PCB to improve signal integrity, increase design flexibility, and optimize thermal performance. These products route high-speed signals through low-loss, low-skew twinax cable and operate across distances that can be up to several feet long while removing the need for clock data recovery circuits (CDRs) or retimers. The high-density 8- or 16-pair configurations offer optimal solutions for routing 4 or 8 channels at 112 Gb/s PAM4 data rates, enabling 25.6 TB aggregate data, and are PCIe 6.0/CXL 3.1 capable. The cable system incorporates 34 AWG Samtec Eye Speed® Ultra Low Skew twinax cable, which delivers tight coupling between signal conductors, low skew (<3.5 ps/meter) over extended lengths, and improved bandwidth and reach. The cable is available in engineered impedance configurations of 92 and 100 ohms. Si-Fly consists of the CPC cable system and CPI board-level interconnect.

SV Microwave's extended ferrule RF cable connectorsSV Microwave’s extended ferrule RF cable connectors feature an extended-length ferrule to protect the solder joints and fragile cable sections from environmental stress. The longer-length ferrule increases durability for use in the field and replaces the need for shrink tubing, making them an ideal solution for Test & Instrumentation applications. This cable connector product line includes threaded male SMA, 2.92 mm and 2.4 mm configurations and female push-on SMP and SMPM configurations.

Rosenberger provides a wide range of compact calibration kitsRosenberger provides a wide range of compact calibration kits in various series of common coaxial connector interfaces: RPC-1.35, RPC-1.85, RPC-2.40, RPC-2.92, RPC-3.50, RPC-N (50 Ω), RPC-N (75 Ω), 7-16, N, 4.3-10, and 4.1-9.5, each male and female. Compact calibration kits combine all necessary calibration standards in one compact unit – small, easy to handle, and lightweight. The 3-in-1 calibration kits can be applied for complete MSO calibrations (open – short – load) of single port vector network analyzers. The 4-in-1 calibration kits can be used for complete MSOT calibrations (open – short – load – thru) of two or more port vector network analyzers. Rosenberger runs its own calibration laboratory accredited and controlled by the German accreditation body DAkkS (Deutsche Akkreditierungsstelle) according to DIN EN 17025.

The ultra-miniature, high-density, and high-speed connectivity solutions in the Fischer MiniMax SeriesThe ultra-miniature, high-density, and high-speed connectivity solutions in the Fischer MiniMax Series offer smaller connectivity that yields big advantages in terms of design integration. For example, the 12 mm diameter receptacle (size 08) with up to 24 power and signal contacts represents up to a 45% space saving compared to standard receptacles with a similar number of contacts. The external dimensions of electronic devices are affected by the growing demand for sensors and mobile (or wearable) electronics as well as for autonomous robotics and vehicles. With up to 75% weight saving, the Fischer MiniMax Series achieves both size and weight reduction, maximizing performance while minimizing the integration burden. The main reliability features of the Fischer MiniMax Series are 5,000 mating cycles, 360° EMC shielding, IP68 sealing -20m/24h, gas tightness to 10-6 mbar l/s, high corrosion resistance, operating temperatures from -40 °C to +135 °C, blind mating, three secure locking mechanisms (quick-release, push-pull, screw), and cable assemblies with straight or angled bend relief overmolding. When ruggedized for durable life cycles, lightweight and ultra-miniature solutions further increase flexibility and facilitates design integration for demanding applications such as testing equipment, instrumentation, defense and security, and unmanned aerial vehicles (UAVs).

CarlisleIT’s RF jumpers for Test & MeasurementCarlisleIT’s RF jumpers for Test & Measurement include multiple configurations available with 1.85 mm, 2.40 mm, 2.92 mm, and 3.50 mm connector types on .079″ (outer shield diameter) coaxial cable. Low insertion loss and VSWR indicate their high quality and performance. Key features and benefits of CarlisleIT’s RF jumpers include armor cables suitable for over bending and high-temperature operations, excellent abrasion and cut-through resistance for Armored Coax Cable Assemblies, and standard RF jumpers phase matched to +/-2 ps in pair. Tighter phase matching to +/-1ps and +/-0.5 ps is available upon request.
