Circular MIL-Spec Product Roundup 

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

Circular MIL-Spec Connectors

JPC’s square-type MIL-DTL-compatible connectors far exceed standard commercial requirements for shock, vibration, and temperature resistance. Their square flange design ensures secure panel mounting, mechanical stability, and easy integration into sealed or reinforced enclosures. Available in both commercial and military-grade configurations, JPC’s connectors include receptacle and plug variants (straight and right-angle) with matte anti-reflective finishes, ensuring long-term durability and corrosion resistance even in outdoor or field-deployed environments. Each connector is engineered for high-current, multi-pin configurations, making it ideal for ground vehicles, radar systems, industrial robotics, aerospace subsystems, and heavy machinery control units. Every unit undergoes rigorous mechanical and environmental testing to ensure stable signal transmission and long operational life in demanding use cases.

CDM now provides the full range of Amphenol NEXUS Technologies military-spec high-performance 5 and 6 contact MIL-DTL-55116 interconnects and accessories in standard and lightweight versions to support military radios, tactical intercom networks, and rugged-environment communications technologies. PCB back-end and right-angle variants are available for unique or specialty applications. This series encompasses waterproof, polarized plugs and receptacles for use in audio frequency circuits at 60 volts maximum potential and 0.5 amperes maximum current. All connectors are rated at up to 3,000 mating cycles. Amphenol NEXUS Technologies, a subsidiary of Amphenol Corporation, is one of the world’s leading manufacturers of interconnect products for defense, industrial and commercial applications.

SV Microwave has developed a new line of D38999 contacts as demand for higher frequency RF tech and increased density in D38999 circular backshell connectors increases. With electrical performance up to 40 GHz, these size 20 and 20HD pin & socket contacts are compatible with Series I, II, III, and IV housings as well as 2M Series 80 housings.

ITT Cannon’s CA Bayonet is widely recognized as the most reliable and versatile series of VG95234 connectors available today. CA Bayonet delivers exceptional quality and performance in the harshest defense applications. The coupling design allows for quick and simple mating and un-mating while delivering the ultimate in shock and vibration protection. CA Bayonet covers the complete range of VG95234 variants, and the extended commercial portfolio is one of the most diverse available. Features include sealing up to IP69k, extreme shock and vibration resistance, and superior shielding performance. RoHS-compliant plating options include VG approved “J” plating, the 1:1 cadmium replacement as defined by VG95234 standard (A241).

Amphenol Pcd M28840 circular connectors according to MIL-DTL-28840 are shipboard application connectors that are precision-machined, highly reliable, and meet superior mechanical shock performances. These high-density connectors are designed and tested to withstand extreme environmental conditions and demanding applications. Amphenol also offers the full range of backshells to support this connector series.
