Heavy-Duty Modular Rectangular Connectors

modular rectangular connectors from HARTING and AlliedAllied Electronics & Automation stocks HARTING’s Han-Modular Series connectors, which allow users to quickly, easily, and cost-effectively create optimized solutions for a wide variety of industrial applications by combining individual modules designed to transmit different media. These modular rectangular connectors are available with sliding, docking, or hinged frames and an extensive range of modules, hoods, housings, and accessories, and they support hybrid combinations of various off-the-shelf multimedia modules, enabling power, signal, data, and even compressed air transmission in space-saving, single-connector solutions with standardized footprints that enable easy integration into both new and existing equipment. The modules were the first smart connectors capable of connecting to the Industrial Internet of Things (IIoT) at the component level and are easy to install, remove, and swap out, enabling extensive design flexibility and fast and easy retrofits within the same standard footprint. They are also available with placeholder modules to support future proofing in application areas with rapidly evolving performance standards.

modular rectangular connectors from SmithsSmiths Interconnect’s HyperMod Series heavy-duty modular rectangular connectors are designed to meet the growing requirement for high-speed signal connections in railway applications and are available with special shells for harsh environments, special high-clearance and -creepage modules, and a wide variety of reliable contacts — all of which conform to DIN 43652 specifications and are approved to NF F 61-030 railway standards. HyperMod connectors have robust, RoHS-compliant, and shock- and vibration-proof aluminum shells that are sealed to IP67 and equipped with highly effective shielding that meet the exacting EMC requirements for railway environments. Housing and hoods are available in a variety of styles with single or double locking systems and can be equipped with modules containing various combinations of fiber optic, high-speed twinax or quadrax Ethernet, power, and signal contacts.

Additional benefits include low insertion force and long lifecycles.

modular rectangular connectors from RadiallRadiall’s EPX – EN 4644 Series modular rectangular connectors are standardized to EN 4644, designed to meet an array of stringent OEM connectivity requirements with the use of a limited number of components, and extensively employed in disconnect panels, line replaceable modules, and galleys within major commercial airlines and business jets. The series provides flexibility with a wide variety of shell styles and a range of inserts, contacts, and accessories, space savings with high-density insert and stackable shell options, and time and cost savings with modular parts that enable prewiring. For example, the modular, expandable series offers lightweight shells from size #1 to multi-gang versions and inserts capable of accepting any contact technology, including signal, power, quadrax, and fiber options. EPX Disconnect Connectors are especially designed for panel integration on EWIS applications, support cable-to-cable and board-to-cable links, and are available in three shell sizes (EPXA1, EPXB1, and EPXB2), each of which features a secure locking device that doesn’t require any additional space for activation. EPXB2 connectors are ideal for use in line replaceable units (LRU) within distributed architectures and also come equipped with a centering guide. EPX Rack & Panel Connectors are compact, lightweight, and high-density, require low mating forces, and can be used on standalone PCB architectures and line replaceable modules (LRM). EPX Series modular rectangular connectors are also resistant to shock and vibration, lightning strikes, EMI, salt spray, and temperature extremes and are rated for a minimum of 100 mating cycles in operating temperatures as low as -65°C and as high as +175°C.

The system complies with IEC 61076-4-107 requirements and features compact rectangular modules with dimensions in accordance with IEC 917 and IEEE P 1301 specifications to ensure easy implementation into both metric and imperial systems. It also has a 2.0mm pitch, a vibration-proof locking mechanism, and EMI shielding designed especially for EMI polluted environments, reliably withstands up to 80N of pull force, and supports 2Gb/s per-pair data rates, hot plugging (as required by modern bus systems including CompactPCI, S-bus, and VME), and high-temperature reflow soldering. In addition to single connector solutions, HARTING also provides cable assemblies with shielded or unshielded twisted pairs for high-speed applications such as IEEE 1355, as well as a crimping tool range for terminating male har-link connectors.

modular rectangular connectors from CinchCinch Connectivity SolutionsC-ENX Series EN 4644 modular rectangular connectors for next-generation aerospace applications are slim, modular, and expandable and comprised of an outer protective shell, sealed inserts, machined contacts, and optional backshells, accessories, and assemblies all standardized to EN 4644. The series offers shells optimized for galley, disconnect, and rack and panel applications and made from aluminum, stainless steel, or composite materials. It also offers small and large inserts that position the contacts, prevent electrical shortages, and provide an environmental seal against corrosive fluids. C-ENX pin and socket inserts are easy to install and remove, can be installed in both plug and receptacle shells, are available in high-density layouts, and accept signal, power, data, RF, and fiber contacts. The series is also available with optional ground blocks to meet FAA HIRF requirements, backshells for strain relief or EMI protection, and accessories ranging from tools to spare parts and dust caps. In addition to providing extensive customization and versatility, C-ENX Series connectors support space-saving stacking configurations that don’t require any additional space to engage locking mechanisms and reduce rework and complexity by using the same panel cutout for all variations and the same shell cavities for all inserts.
