Positronic, a leading global manufacturer of high reliability electronic connectors and division of the Amphenol Corporation (NYSE: APH), announces the release of its MACH-D D-Sub connector family for use in harsh environments.

MIL-DTL-24308-style D-Subminiature connectors are increasingly popular in harsh environment applications such as deep space, defense electronics, commercial aircraft, medical devices, and more. The MACH-D family of products, designed for use in next generation harsh environments, is the newest member of the industry-leading D-Sub connector lineup from Positronic. All MACH-D products boast machined aluminum or stainless steel shells for the ultimate in durability, precision, planarity, and electromagnetic compatibility.

These machined shells are the primary differentiator between MACH-D products and their M24308 cousins, which are only available in stamped shells. Despite this difference in shell construction, MACH-D connectors are fully intermateable with standard M24308-type D-Subs and, in many cases, outperform the minimum requirements as outlined in MIL-DTL-24308. Additionally, MACH-Ds are performance-comparable and mechanically compatible with Glenair’s Series 28 HiPer-D® connectors.

MACH-D products are available in standard and high density signal contact arrangements as well as hybrid versions, which combine power and signal in a single connector body. Unique accessory options include keyed jackscrews, rear silicone grommets, interfacial seals, EMI grounding strips, and a 360-degree banding feature useful when space limitations preclude the use of a full-size backshell. Custom options are available on request. Customer-friendly configurators for MACH-D products are available both online at and in print.

Founded in 1966 and acquired by Amphenol in 2021, Positronic is a global manufacturer of highly reliable electronic connectors known for its distinctive core capability manufacturing solid machined contacts with low resistance/high conductivity for use in standard and quick-turn custom connectors. Key products include power, D-Sub, modular, and other rectangular connectors. Customized solutions are available as well. Click here for more details.
