Installation: compatible with standard size 18 crimp or solder contacts and typical cabletermination practices for MSseries connectors. Why customers choose this model Militarygrade reliability without guessing compatibility — MS3102A2018S follows established MSseries conventions so it mates predictably with matching receptacles and accessories. Compact shell size 20 balances space savings with robust contact capability. Proven formfactor used across aviation, defense, and industrial applications where downtime and signal integrity are not acceptable. Typical applications Aircraft and avionics wiring harnesses — secure connections for instruments, navigation, sensors, and onboard power circuits. Military vehicles and ground support equipment — durable interconnects for communications, control circuits, and ruggedized electronics. Industrial and test systems where a compact, militarystandard circular plug is required for reliable signal and power connections. Installation and compatibility notes Ensure correct size 18 contacts and compatible mating receptacle (MSseries) are used to maintain militarystandard performance. Use appropriate crimp tools or soldering procedures for the chosen contacts to ensure mechanical and electrical integrity. When EMI protection or sealing is required, pair the plug with compatible backshells, grommets, and receptacles rated for the intended environment. If you need a compact, proven U.S. military standard aviation plug for reliable power and signal connections, the MS3102A2018S is engineered to meet those requirements while fitting standard MSseries systems.
