MIL-DTL-24308 D-Sub Plug — 25 Position, Crimp

Specifications

Cross-Reference

Overview

The M24308-4-261Z is a MIL-DTL-24308 D-subminiature connector — m24308/4 plug, crimp type, 25 (shell size B) positions, pin (male) contacts, crimp, removable termination. MIL-DTL-24308 (formerly MIL-C-24308 and MIL-PRF-24308, currently at Revision G) is the DLA Land and Maritime specification for polarised-shell rack-and-panel connectors, and the legacy MS18269–MS18276 detail sheets have been progressively rolled into the current M24308/1 through M24308/24 slash-sheet series.

The connector uses a trapezoidal metal shell with two or more parallel rows of pin-and-socket contacts on standard density size-20 contacts, rated 7.5 A per contact, with gold over nickel plating in the mating area and a glass-filled diallyl phthalate insulator. Durability is 500 mating cycles and the operating temperature range spans the military band. Because MIL-DTL-24308 is a non-environmental specification, the connector is not sealed against moisture or fluids — it is intended for controlled rack, panel and cabinet environments rather than exposed airframe or engine-bay locations.

Over 2,300 QPL part numbers exist across the slash sheets, covering classes G, N, M and D (general, space and non-magnetic) and a choice of crimp, solder cup, and straight or right-angle PCB terminations. Shell plating options include cadmium, zinc, zinc-nickel and passivated stainless steel; the F suffix denotes yellow chromate cadmium and the Z suffix yellow chromate zinc. The same shell dimensions are shared commercially under IEC 60807-3 and DIN 41652, so M24308 bodies fit standard commercial D-sub hardware and backshells.

Applications

Military and aerospace rack-and-panel signal interconnect, avionics and instrumentation harnesses, ground-support and test equipment, missile and satellite subsystems, naval electronics, and industrial rack equipment where a polarised, high-reliability D-sub interface is required.
