Knowing Military Connector Specs

From the connector field, there are plenty of complex terms which might in some cases be challenging to decipher. Military connectors desire by their very character which they meet the stringent technical criteria at first laid out because of the US Division of Protection.

They as well as their derivatives are commonly often called Military Typical, MIL-STD, or MIL-SPEC connectors. In this article, we glance at a few of the most common technical specs and specifications and explain what exactly they necessarily mean.


Previously called MIL-C-38999, MIL-DTL-38999 connectors undoubtedly are a series of four connectors which can be comprised of bayonet, threaded, and Breech Lok coupling mechanisms. They are really environmentally resistant connectors that use removable crimp contacts and also have an functioning range of -sixty five to +two hundred°C.

Sequence I connectors are bayonet coupled and also have substantial-vibration Homes. They're scoop proof and are ideal for large wind and humidity environments. They are utilised every time a quick disconnect coupling process is necessary.

Collection II connectors are bayonet coupled, are non-scoop proof, and have a reduced profile, so are applied when fat or Place is restricted, or in very low-vibration, higher dampness, and robust wind scenarios.

Sequence III connectors are coupled by a quick screw Tri begin thread, are scoop proof, and they are most effective suited to normal mating and unmating purposes and may be used in higher temperature, military connectors moisture, wind, or vibration environments when utilised with the right equipment.

Sequence IV connectors are coupled by a Breech Lok mechanism, are scoop evidence, lightweight and appropriate for blind mating apps, they usually also have higher-vibration characteristics. They may be like minded in superior wind and moisture environments when applied with the appropriate add-ons. Insert preparations for all series are presented in MIL-STD-1560. FC Lane Electronics Ltd is a leading Price Included Distributor with the SOURIAU Connection Technologies variations of your MIL-DTL-38999 sequence one and 3.


MIL-DTL-26482, previously referred to as MIL-C-26482, are bayonet lock connectors, and series one (solder) and sequence 2 (crimp) cover the requirements for 2 number of miniature, fast disconnect, ecosystem resisting, round electrical connectors and their equipment. Equally collection include hermetic receptacles and so are intermateable when used with normal contacts and non-intermateable when utilised with shielded contacts.

The kinds and courses of connector involve courses E, F, J, and P, which happen to be utilised in surroundings-resisting predicaments and possess an running variety of -55 to -one hundred twenty five°C. Class H receptacles are suited to situations exactly where pressures/vacuums are needed to be maintained while in the boxes/vessels that the connector is mounted to.

There are plenty of works by using for this connector outside of the Formal armed service specification as well as the specification features two round connector collection: Collection I incorporates MS3110, MS3111, MS3112, MS3114, and MS3116, and Sequence II contains MS3470, MS3474, MS3475, and MS3476 connectors. Insert preparations are provided in MIL-STD-1669. The Weald Electronics Ltd version may be the LMH range of connectors and components that are suitable with sequence 1 (solder). These products are thoroughly stocked and distributed by FC Lane Electronics Ltd.



The MIL-DTL-5015 conventional, Beforehand often called MIL-C-5015, describes round connectors which have entrance and rear release crimp contacts together with solder contacts. They can be used in electrical energy, electronic, and Manage circuits and they are greatly used in industrial, civil, and protection purposes as These are available, functional and responsible. They may have an operating array of -55°C to possibly a hundred twenty five°C, one hundred seventy five°C, or 200°C according to the connector class. Insert preparations are offered in MIL-STD-1651. The Weald Electronics Ltd Model is the LMJ number of connectors, which has solder contacts. These products and solutions are thoroughly stocked and distributed by FC Lane Electronics Ltd.


This typical, MIL-DTL-24308 (formerly known as MIL-C-24308), describes non-environmental, polarised shell, rack and panel, miniature connectors with pin and socket, solder (non-detachable), insulation displacement (non-detachable), or crimp (detachable) float-mounting or rigid mounting brackets. They have got an working temperature array of -fifty five°C to one hundred twenty five°C.

They may be generally known as D-Subminiature or D-sub connectors and so are used in environments where by fat and Area absolutely are a thing to consider, although accommodating lots of circuits in relation to their dimensions. For this reason they are perfect for missiles, plane, and ground guidance methods. Aside from rack and panel purposes, these will also be tailored to be used by utilising integral clamps and also other similar equipment.

They may be designed for use in army apps as follows: classes G and N are for use in just environments with the running number of -fifty five°C to 125°C (class N are Employed in environments where by residual magnetism ought to be held at minimal stages), class H are utilized when pressures/vacuums should be maintained within the boxes/vessels on to which the connectors are mounted, and classes D, K, and M are intended to be used in large-reliability Place programs. FC Lane Electronics Ltd thoroughly stocks and distributes solutions from Positronic Industries that handles equally the MIL specification and commercial versions of this sort of connector.


Earlier called MIL-C-83513, the MIL-DTL-83513 specification describes micro-miniature, polarised shell rectangular connectors which have solder or non-detachable crimp contacts. They can be tricky-putting on and long-lasting and as such are meant for use in harsh environments, obtaining significant dielectric power, significant current capacity, very low Speak to resistance, and higher resistance to vibration and shock. They're light-weight, of little size, and have a high density of pins.

They are also known as Micro-D connectors and due to their tiny dimension and body weight, are commonly used in radars, shoulder-launched weapons, armed forces GPS, health-related machines, satellites, drilling resources, Superior soldier technological innovation, and aerospace avionics applications.


The common that designers want when an application needs minimum utilization of space and fat without any sacrifice inside the general performance. Other demands of MIL-DTL-28748 consist of the usage of large-excellent components, a significant resistance to shock and vibration, constructive locking and a lengthy everyday living. This specification is typically used in aerospace, instrumentation and For most kinds of moveable equipment. Formerly acknowledged simply just as M28748, substantial density and standard density MIL-DTL-28748 product or service ranges are made up of rectangular rack and panel connectors with non-removable solder contacts and removable crimp contacts.
