Comprehension Military Connector Requirements

Knowing Military Connector Technical specs™

From the connector business, there are numerous technological terms which might often be difficult to decipher. Military connectors desire by their pretty nature which they meet the stringent specialized benchmarks originally laid out because of the US Division of Defense.

They and their derivatives are commonly generally known as Military Common, MIL-STD, or MIL-SPEC connectors. In this post, we look at some of the most typical technical specs and expectations and make clear exactly what they imply.



Earlier called MIL-C-38999, MIL-DTL-38999 connectors absolutely are a series of four connectors that are comprised of bayonet, threaded, and Breech Lok coupling mechanisms. They are really environmentally resistant connectors that use detachable crimp contacts and also have an running range of -sixty five to +two hundred°C.

Sequence I connectors are bayonet coupled and also have large-vibration Qualities. They are scoop evidence and are perfect for significant wind and moisture environments. They can be utilised when a rapidly disconnect coupling procedure is needed.

Series II connectors are bayonet coupled, are non-scoop proof, and possess a very low profile, so are used when body weight or Place is limited, or in very low-vibration, substantial humidity, and robust wind scenarios.

Sequence III connectors are coupled by a quick screw Tri get started thread, are scoop evidence, and therefore are finest fitted to ordinary mating and unmating programs and can be employed in substantial temperature, dampness, wind, or vibration environments when applied with the right equipment.

Sequence IV connectors are coupled by a Breech Lok system, are scoop evidence, light-weight and ideal for blind mating apps, they usually even have substantial-vibration characteristics. They are well suited in significant wind and moisture environments when made use of with the right components. Insert arrangements for all sequence are supplied in MIL-STD-1560. FC Lane Electronics Ltd is a leading Value Included Distributor for that SOURIAU Relationship Technologies variations with the MIL-DTL-38999 series 1 and 3.


MIL-DTL-26482, Formerly called MIL-C-26482, are bayonet lock connectors, and series one (solder) and collection two (crimp) cover the requirements for 2 number of miniature, swift disconnect, atmosphere resisting, round electrical connectors and their components. Both collection incorporate hermetic receptacles and they are intermateable when made use of with standard contacts and non-intermateable when employed with shielded contacts.

The types and classes of connector consist of lessons E, F, J, and P, that happen to be utilised in atmosphere-resisting situations and have an running array of -fifty five to -a hundred twenty five°C. Course H receptacles are appropriate for circumstances where by pressures/vacuums are required to be taken care of in the bins/vessels the connector is mounted to.

There are various works by using for this connector beyond the official army specification and the specification incorporates two circular connector series: Series I consists of MS3110, MS3111, MS3112, MS3114, and MS3116, and Collection II consists of MS3470, MS3474, MS3475, and MS3476 connectors. Insert arrangements are presented in MIL-STD-1669. The Weald Electronics Ltd version could be the LMH variety of connectors and accessories which might be suitable with series one (solder). These items are thoroughly stocked and distributed by FC Lane Electronics Ltd.


The MIL-DTL-5015 common, Earlier generally known as MIL-C-5015, describes round connectors that have entrance and rear launch crimp contacts and also solder contacts. They can be Utilized in electrical ability, Digital, and Handle circuits and are extensively Employed in industrial, civil, and defense applications as They may be available, adaptable and dependable. They have got an functioning array of -fifty five°C to either a hundred twenty five°C, 175°C, or two hundred°C depending upon the connector course. Insert preparations are supplied in MIL-STD-1651. The Weald Electronics Ltd Edition will be the LMJ number of connectors, which has solder contacts. These products and solutions are extensively stocked and distributed by FC Lane Electronics Ltd.


This common, MIL-DTL-24308 (previously known as MIL-C-24308), describes non-environmental, polarised shell, rack and panel, miniature connectors with pin and socket, solder (non-removable), insulation displacement (non-removable), or crimp (removable) float-mounting or rigid mounting brackets. They may have an working temperature variety of -fifty five°C to a hundred twenty five°C.

They are also known as D-Subminiature or D-sub connectors and so are used in environments wherever body weight and Area can be a thing to consider, even though accommodating a great deal of circuits in relation for their dimensions. Because of this they are ideal for missiles, aircraft, and floor aid techniques. Besides rack and panel applications, these can also be tailored to be used by utilising integral clamps together with other linked equipment.

They're suitable for use in army apps as follows: courses G and N are to be used within environments with the running choice of -55°C to one hundred twenty five°C (course N are used in environments exactly where residual magnetism has to be held at reduced levels), course H are employed when pressures/vacuums have to be managed during the boxes/vessels onto which the connectors are mounted, and classes D, K, and M are meant to be used in superior-dependability Place apps. FC Lane Electronics Ltd extensively stocks and distributes products from Positronic Industries that handles both equally the MIL specification and industrial variations of the form of connector.


Earlier named MIL-C-83513, the MIL-DTL-83513 specification describes micro-miniature, polarised shell rectangular connectors that have solder or non-detachable crimp contacts. They may be challenging-carrying and long-lasting and therefore are meant to be used in harsh environments, possessing substantial dielectric power, superior present-day capability, minimal Speak to resistance, and large resistance to vibration and shock. These are lightweight, of small dimensions, and also have a substantial density of mil-dtl-38999 connectors pins.

They are really often known as Micro-D connectors and because of their smaller size and body weight, are generally used in radars, shoulder-introduced weapons, armed forces GPS, clinical machines, satellites, drilling equipment, Innovative soldier technological innovation, and aerospace avionics applications.


The standard that designers motivation when an application calls for nominal usage of House and body weight with no sacrifice while in the overall performance. Other requirements of MIL-DTL-28748 involve the usage of large-high-quality products, a high resistance to shock and vibration, favourable locking and an extended life. This specification is usually Employed in aerospace, instrumentation and For a lot of varieties of portable equipment. Formerly recognized simply as M28748, high density and conventional density MIL-DTL-28748 products ranges are created up of rectangular rack and panel connectors with non-removable solder contacts and removable crimp contacts.
