MIL-DTL-26482 Series 2 is the rear-release crimp version of the 26482 bayonet connector. It is specified on most new-build harnesses that call for 26482 and it intermates with the Series 1 shells already in the field. Shell styles MS3470: wall-mount receptacle MS3471: cable-connecting receptacle MS3474: jam-nut receptacle MS3475: box-mount receptacle MS3476: straight plug MS27476: earlier…

MIL-DTL-38999 Series I connectors keep the same basic number system as the Series III D38999 family, but the prefixes are MS drawings instead of slash sheets. Here is how to read them. The two most common numbers MS27467: straight plug (mates with any Series I receptacle) MS27473: wall-mount receptacle, crimp contacts (current design; MS27466 is…

MS3100-series connectors (MS3100, MS3101, MS3102, MS3106, MS3108) ship without strain relief. The MS3057 cable clamp threads onto the rear of the connector and grips the cable; the MS3420 bushing sits inside the clamp and adapts it to the cable diameter. MS3057 dash number by shell size Clamp Fits shell sizes MS3057-3A 8S, 10S, 10SL MS3057-4A…

Every M85049 slash sheet is written for a specific set of connector families. Pick the wrong one and the threads will not engage. Here is the map. D38999 Series III and IV: M85049/38 and /39 The /38 is straight, the /39 is 90 degree. Dash numbers 9 through 25 equal the connector shell size (9,…

MS3180 and MS3181 are the protective covers for MIL-DTL-26482 bayonet connectors (MS3110 to MS3128 Series 1 and MS3470 to MS3479 Series 2). They are the most requested covers we stock, and the suffix letters cause the most confusion. MS3180: receptacle cover MS3180 has bayonet pins like a plug and caps a receptacle (MS3110, MS3112, MS3114,…

Ask ten buyers which cap goes on a MIL-DTL-5015 plug and half will get it backwards. The rule is simple once you see the geometry. MS25042 covers receptacles An MS25042 cap is shaped like a plug: it has external threads that screw into the coupling ring of a receptacle (MS3100, MS3101, MS3102, MS3450, MS3451, MS3452)….

MS3116 vs MS3476: solder vs crimp, class letters, insert arrangements, MS3180/MS3181 covers, and which Series 1 and Series 2 parts actually intermate.

How to tell D38999 Series III from MS27467 Series I: coupling, class letters, part-number anatomy, and why the two series do not mate.

What MIL-PRF-39012 and UG-series RF connector designations mean, which BNC, TNC and Type N interfaces they cover, and why buying Delta Electronics parts through a franchise distributor matters for traceability.

A practical guide to MIL-DTL-85049 backshells: what the slash sheet means (/38, /39, /49, /51, /52), how to match shell size and finish to the connector, and when to use a self-locking version.
