This week’s Product Roundup highlights Rectangular MIL-spec connectors from leading connector manufacturers and  suppliers.

Rectangular MIL-spec Connectors

Nicomatic has an extensive range of MIL-Spec rectangular connectors.Nicomatic has an extensive range of MIL-Spec rectangular connectors. The CMM Series provides a modular rectangular connector platform that integrates signal, power, and RF contacts within a single interface. Available in multiple sizes and configurations, the CMM range is widely used in embedded electronics, avionics, and defense systems requiring high density and mixed technologies. The EMM Series and AMM Series offer rectangular solutions suited to space-constrained architectures. These connectors are designed to withstand high levels of vibration and are available with a variety of contact configurations and termination options. Nicomatic also supplies custom cable assemblies and sub-assemblies, enabling complete interconnect solutions qualified at system level. Testing and qualification can be carried out in Nicomatic’s internal laboratories to accurately replicate real application conditions.

Ulti-Mate’s Micro-D Connectors from Winchester,Ulti-Mate’s Micro-D Connectors from Winchester, built around the MIL-DTL-83513 interface, deliver exceptional electrical and mechanical performance in a miniaturized package. These connectors are engineered for systems where shock, vibration, temperature extremes, and long-term reliability cannot be compromised, such as missile guidance packages, avionics modules, and soldier-borne electronics. Precision-machined shells, tightly controlled contact retention, and multiple termination styles (including solder cup, pre-wired, and PCB tail) give designers the flexibility to integrate Micro-D connectors into both legacy and next-generation platforms. For extreme SWaP constraints, Ulti-Mate’s Nano-D Connectors offer an even smaller, higher-density architecture. Designed around the MIL-DTL-32139 footprint, these nanominiature connectors provide reliable signal integrity in packages often smaller than a fingernail, making them ideal for applications such as UAV flight controls, medical implants, micro-sensors, and space-constrained missile subsystems. Their high-precision stamped or machined contacts, robust latching systems, and proven mating cycles allow engineers to reduce size and weight

With more than 2,500 configurations, the KA Series from Smiths InterconnectWith more than 2,500 configurations, the KA Series from Smiths Interconnect provides design flexibility and supports a current rating of up to 9 Amps per contact. Utilizing the field-proven capabilities of the Hypertac hyperboloid contact technology, the KA Series provides immunity to detrimental fretting due to shock and vibration, industry-leading mating cycles, and durability in a connector that meets the performance requirements of MIL-DTL-55302.

ITT Cannon MIL-DTL-83513 Series Micro-D interconnects and cable assembliesITT Cannon MIL-DTL-83513 Series Micro-D interconnects and cable assemblies are ideally suited for applications requiring extremely small, lightweight, and ruggedized solutions with higher density contact configurations. M83513 Micro-D connectors are available in eight shell sizes that accommodate 9 to 100 contacts. These robust, space-saving MIL-DTL-83513 qualified interconnects meet ongoing industry demand for environmental, high performance, and moisture-sealed micro connectors that perform reliably in the harshest environments. Our 83513 Micro-D connectors are ideally suited for missiles and ordnance, aerospace launch vehicles, oil & gas exploration, and industrial automation applications.

Amphenol's D-Sub high performance board-mount connectorsAmphenol’s D-Sub high performance board-mount connectors are designed for severe environment applications in the field of telecommunications, aerospace, military (125 °C) class, and for particularly severe applications, especially high temperature (+155 °C) class. They feature machined contacts and are available in solder bucket, straight spills, angled spills, and wire wrap terminations. The DP Series of connectors has application in data transmission, private automatic branch switching, and telecom (LNZ listed). The products are UL recognized and lead-free.

Gladiator from Amphenol PCD is a small, lightweight, flat connector designed for soldier worn applications which include data sharing, battery charging, and peripheral connectivity. Plugs and receptacles fit through MOLLE pack straps. Receptacles are designed for panel mounting, clipped into MOLLE, or sewn into place. Magnetic mating orients and aligns connectors for fast, no-look mating. Factory adjustable engage/disengage forces meet customer specific requirements. Spring pins (spring probes) maintain contact through shock and vibration. A fluorosilicone gasket interfacial seal seals individual contacts and the plug to the receptacle.
