Comprehension Military Connector Specs

While in the connector sector, there are plenty of technical phrases which could from time to time be hard to decipher. Military connectors need by their extremely character that they meet up with the stringent technological expectations initially laid out from the US Division of Defense.

They as well as their derivatives are commonly known as Military Normal, MIL-STD, or MIL-SPEC connectors. In this article, we glance at some of the commonest technical specs mil-dtl-38999 connectors and standards and explain what exactly they necessarily mean.


Previously generally known as MIL-C-38999, MIL-DTL-38999 connectors really are a number of 4 connectors which are comprised of bayonet, threaded, and Breech Lok coupling mechanisms. They are really environmentally resistant connectors that use removable crimp contacts and have an running array of -sixty five to +200°C.

Collection I connectors are bayonet coupled and possess high-vibration Qualities. They are really scoop proof and are ideal for hefty wind and dampness environments. They are utilised each time a quick disconnect coupling process is required.

Sequence II connectors are bayonet coupled, are non-scoop evidence, and possess a low profile, so are utilized when fat or Room is limited, or in small-vibration, substantial dampness, and powerful wind situations.

Sequence III connectors are coupled by a quick screw Tri start out thread, are scoop evidence, and so are finest suited for regular mating and unmating applications and can be employed in substantial temperature, moisture, wind, or vibration environments when made use of with the right components.

Sequence IV connectors are coupled by a Breech Lok mechanism, are scoop evidence, light-weight and well suited for blind mating purposes, plus they also have large-vibration attributes. They are well suited in substantial wind and humidity environments when used with the suitable components. Insert arrangements for all series are presented in MIL-STD-1560. FC Lane Electronics Ltd is a number one Benefit Additional Distributor with the SOURIAU Link Systems variations of the MIL-DTL-38999 collection 1 and three.


MIL-DTL-26482, Formerly known as MIL-C-26482, are bayonet lock connectors, and collection one (solder) and sequence two (crimp) address the requirements for two number of miniature, brief disconnect, atmosphere resisting, circular electrical connectors as well as their components. The two sequence include hermetic receptacles and therefore are intermateable when made use of with standard contacts and non-intermateable when utilised with shielded contacts.

The kinds and lessons of connector incorporate classes E, File, J, and P, which are utilised in environment-resisting situations and also have an running selection of -fifty five to -a hundred twenty five°C. Course H receptacles are suited to situations wherever pressures/vacuums are needed to be managed during the boxes/vessels which the connector is mounted to.

There are several employs for this connector outside of the official armed service specification as well as the specification contains two circular connector sequence: Sequence I incorporates MS3110, MS3111, MS3112, MS3114, and MS3116, and Collection II includes MS3470, MS3474, MS3475, and MS3476 connectors. Insert arrangements are delivered in MIL-STD-1669. The Weald Electronics Ltd Edition could be the LMH choice of connectors and extras which are suitable with sequence one (solder). These merchandise are thoroughly stocked and dispersed by FC Lane Electronics Ltd.


The MIL-DTL-5015 typical, Formerly called MIL-C-5015, describes round connectors which have front and rear launch crimp contacts in addition to solder contacts. They are used in electrical ability, Digital, and Handle circuits and they are broadly Utilized in industrial, civil, and defense purposes as They are really available, functional and reputable. They have an working number of -55°C to possibly a hundred twenty five°C, 175°C, or 200°C dependant upon the connector course. Insert arrangements are provided in MIL-STD-1651. The Weald Electronics Ltd Model is the LMJ number of connectors, that has solder contacts. These items are thoroughly stocked and distributed by FC Lane Electronics Ltd.



This conventional, MIL-DTL-24308 (formerly often called 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've an running temperature selection of -55°C to a hundred twenty five°C.

These are generally known as D-Subminiature or D-sub connectors and are used in environments exactly where weight and House absolutely are a consideration, although accommodating loads of circuits in relation for their dimension. Because of this they are ideal for missiles, aircraft, and ground assist devices. In addition to rack and panel apps, these may also be tailored to be used by utilising integral clamps and also other associated extras.

These are created for use in armed service programs as follows: classes G and N are to be used within just environments for the running range of -fifty five°C to a hundred twenty five°C (course N are Employed in environments in which residual magnetism must be held at minimal concentrations), class H are utilised when pressures/vacuums have to be managed in the boxes/vessels onto which the connectors are mounted, and courses D, K, and M are supposed for use in substantial-reliability Area apps. FC Lane Electronics Ltd thoroughly stocks and distributes products from Positronic Industries that covers 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. These are difficult-sporting and long lasting and as such are intended to be used in harsh environments, obtaining significant dielectric toughness, substantial recent functionality, lower contact resistance, and large resistance to vibration and shock. They're lightweight, of smaller sizing, and possess a large density of pins.

They are really also referred to as Micro-D connectors and because of their small size and pounds, are commonly Utilized in radars, shoulder-launched weapons, armed service GPS, health care gear, satellites, drilling tools, Innovative soldier technologies, and aerospace avionics programs.


The conventional that designers wish when an application needs nominal use of Place and pounds with none sacrifice inside the efficiency. Other requirements of MIL-DTL-28748 consist of the use of substantial-good quality products, a superior resistance to shock and vibration, optimistic locking and a lengthy existence. This specification is typically Employed in aerospace, instrumentation and for many varieties of portable tools. Beforehand known simply as M28748, large density and normal density MIL-DTL-28748 item ranges are created up of rectangular rack and panel connectors with non-removable solder contacts and removable crimp contacts.
