Micro-D connectors are about half the size of D-sub connectors. Both are shaped like the letter D. The early D-shaped connectors were first used in computers because of their compact design.

Offering reliable and secure electrical connections, they feature at least two rows of parallel pins and offer high density in a miniature design. The D-shaped socket or plug also provides shielding from EMI. This fits snugly into the receptacle, providing a secure mechanical attachment as well as proper alignment and fit.
Although commonly used on computers, gaming consoles and for networking and communications, these designs are used actively in industrial settings, particularly in aerospace. Most are built to meet the requirements of the MIL-DTL-83513 specifications. They can be made available with Space-grade ratings as well.
Micro-D connectors can also be manufactured for use with PCB cable assemblies because they save valuable wiring space.
These miniature connector designs offer high dielectric strength. They also provide low contact resistance and high current capabilities. Additionally, they are extremely resistant to shock and vibration because of their rectangular shield and a screw design that ensures tight mating.
Shell materials can be manufactured of metal or plastic depending on the application.

Traditionally, designers have spent days creating models for each component in their designs, a tedious and time-consuming process. Some components, such as connectors, are particularly challenging to create models for due to their non-standard shapes, pitches, pads, and cutouts.
Pasternack’s new series of high-speed end launch connectors is comprised of four models that provide VSWR as low as 1.10:1 and a maximum operating frequency of 40 to 110 GHz. Connector options include 1.0 mm end launch (110 GHz), 1.85 mm end launch (67 GHz), 2.92 mm end launch (40 GHz) and 2.4 mm end launch (50 GHz). These high-performance end launch connectors don’t require soldering, are reusable and have a compact profile with a 0.350-in. mounting width. They feature an outer conductor made of stainless steel and a gold-plated beryllium copper center contact. These high-speed end launch connectors are ideally suited for high-speed digital and mmWave system development.
Archer Kontrol products can be supplied in either horizontal or vertical orientations (different height options being offered for the vertical models). These space-saving connectors are configured for surface mounting, thereby facilitating automated assembly processes, with hold-down solder tabs ensuring greater retention to the PCB. Thanks to their fully shrouded design, they are able to withstand the lateral and twisting forces that can be encountered in vibration-prone application settings. Furthermore, the polarization of the shroud assists in cases where blind mating is required, and can tolerate a significant amount of misalignment.
Designed for high-density switches with 48 or 64 silicon port designs, TE’s new zQSFP+ stacked belly-to-belly cages address the requirements for higher density switch designs, including Open Compute Project (OCP) reference designs. By supporting a single PCB architecture in each line card, these products reduce design and manufacturing costs. Like the rest of TE’s zQSFP+ portfolio, these cages support up to 28G NRZ and 56G PAM-4 data rates to achieve faster speeds in these high-density switches. TE’s zQSFP+ stacked belly-to-belly cages are dual-sourced with Molex and are drop-in replacements.
The FH63 series offers high contact reliability via a two-point contact design with two independent springs that provide a wiping action that prevents contact failure from dust, dirt and other contaminants. The FPC connector has a user-friendly design, which includes wide tapers that provide smooth FPC insertion. Although the tapers and spring contact mechanism offers a low insertion force, the connector produces a high-retention force for improved reliability in demanding automotive applications such as car navigation, laser radar, millimeter-wave radar, drive recorder, audio display and in-vehicle camera systems.
The company is now offering ODU MEDI-SNAP, a lightweight autoclavable connector available for purchase online at store.odu-usa.com. Additional product features include: high chemical resistance, 2000+ mating cycles, versatile coding possibilities, sterilisable and economical housing.
Designed with an ultra-low profile and space-saving receptacle, the BF4M Series optical interconnects support high-speed isolated signal transmission from 0.05 up to 6.25 Gbps and long distance transmission up to 100 m. The user-friendly optical connector features an innovative internal wiring system that offers all the benefits of fiber optic signaling including high signal quality, low power consumption (less than 120 nW), and excellent EMI noise prevention. The BF4M uses high flex fiber optic cable capable of withstanding significant bending cycles tested at a 2mm bending radius.
In combination with high-speed data cables with transmission rates of up to 10 GBit/s, the molded M12 and RJ45 connectors guarantee a faster and more reliable connection within control cabinets, machinery and in-the-field operations. The cable/connector combinations are directly related to the customer’s intended application use — static, occasional movement, or continuous-flex.
The following is summary of each reason to consider utilizing flat cables instead of round:
The Jonhon JHA series electrical circular connector offers quick bayonet coupling, small packaging that is lightweight, and high density. The MIL-C-38999 I-compliant connectors provide EMI/RFI shielding and withstand strong vibrations, making them ideal for military systems such as aviation, aerospace, and weaponry.
Supporting high-speed applications, the dual row CX90B1 series USB 3.1 Gen2 Type-C compliant interface connector delivers up to 10 Gbps. The SMT connector features a symmetrical mating design that allows for reversible plug insertion. To improve mounting accuracy, the CX90B1 Series has built-in guide posts that ensure precise connector positioning and orientation on the PCB.
It’s not unusual for engineers to turn to nature to help create new designs. This was the case when teams from igus turned needed to create a time and space saving device for product designers.
Binder USA LP has added the M8 12-pin to its series 718 and 768 lines of M8 connectors. The 12 gold-plated contacts allow for more data connections in a small form connector, making it easy to combine multiple connections into one connector to save panel space. The IP67 rated connectors are typically used with automation-related products including photoelectric, proximity and temperature sensors.
Designed for use in solid-state lighting (SSL), industrial machine control, sensor, smart grid, building control, security system, and other ruggedized, space-constrained board-to-board, module-to-module, and wire-to-board applications, both versions of the poke-home contact feature a closed, dual-beam, high-spring-force, box contact design with robust, fatigue-resistant, phosphor bronze contact beams and an integral centering guide, ensuring proper positioning and providing maximum mechanical stability and wire/pin retention strength. In addition, the variant without a wire stop allows traditional pin jumpers to pass through the back of the contact unrestricted, rather than halting their travel at the back of an insulator, effectively absorbing variable PCB and module mating tolerances in linear board-to-board applications.
Würth Elektronik eiSos has expanded its portfolio of board-to-board connectors. Under the designation WR-BTB, the manufacturer of electronic and electromechanical components offers a broad spectrum of plugs and receptacles. Examples for the new SMT assembly connectors are plugs and receptacles with collars and chamfers in 1.00 and 0.80 mm pitch.
