Comprehension Military Connector Specs

Comprehending Military Connector Requirements™

During the connector sector, there are various technological terms which can sometimes be hard to decipher. Military connectors need by their really character which they satisfy the stringent technological criteria originally laid out through the US Office of Defense.

They and their derivatives are generally called Military Conventional, MIL-STD, or MIL-SPEC connectors. On this page, we glance at a few of the commonest specifications and benchmarks and make clear what precisely they signify.


Earlier often called MIL-C-38999, MIL-DTL-38999 connectors undoubtedly are a number of four connectors which might be comprised of bayonet, threaded, and Breech Lok coupling mechanisms. These are environmentally resistant connectors that use detachable crimp contacts and also have an running variety of -sixty five to +200°C.

Series I connectors are bayonet coupled and have significant-vibration properties. These are scoop proof and are perfect for major wind and humidity environments. They can be utilised each time a rapid disconnect coupling process is required.

Collection II connectors are bayonet coupled, are non-scoop proof, and possess a low profile, so are made use of when fat or House is limited, or in lower-vibration, high humidity, and powerful wind conditions.

Series III connectors are coupled by a quick screw Tri start out thread, are scoop proof, and they are most effective fitted to standard mating and unmating programs and can be used in high temperature, moisture, wind, or vibration environments when utilised with the correct components.

Collection IV connectors are coupled by a Breech Lok mechanism, are scoop proof, lightweight and appropriate for blind mating apps, they usually also have significant-vibration characteristics. These are like minded in military plugs connectors higher wind and moisture environments when employed with the suitable add-ons. Insert preparations for all sequence are offered in MIL-STD-1560. FC Lane Electronics Ltd is a number one Value Added Distributor for that SOURIAU Relationship Systems versions on the MIL-DTL-38999 series one and three.


MIL-DTL-26482, Formerly referred to as MIL-C-26482, are bayonet lock connectors, and series 1 (solder) and series two (crimp) deal with the requirements for 2 series of miniature, brief disconnect, ecosystem resisting, round electrical connectors and their equipment. Equally sequence include things like hermetic receptacles and therefore are intermateable when made use of with common contacts and non-intermateable when used with shielded contacts.

The kinds and classes of connector include things like classes E, F, J, and P, which can be utilised in setting-resisting circumstances and have an operating range of -fifty five to -125°C. Class H receptacles are suitable for predicaments exactly where pressures/vacuums are necessary to be taken care of within the containers/vessels which the connector is mounted to.

There are various uses for this connector outside of the Formal military specification as well as the specification features two round connector collection: Collection I consists of MS3110, MS3111, MS3112, MS3114, and MS3116, and Series II involves MS3470, MS3474, MS3475, and MS3476 connectors. Insert preparations are offered in MIL-STD-1669. The Weald Electronics Ltd version would be the LMH array of connectors and extras which might be compatible with collection one (solder). These goods are thoroughly stocked and distributed by FC Lane Electronics Ltd.


The MIL-DTL-5015 normal, Beforehand called MIL-C-5015, describes round connectors that have front and rear launch crimp contacts together with solder contacts. They can be Employed in electrical ability, Digital, and Manage circuits and are extensively Utilized in industrial, civil, and defense applications as They may be readily available, adaptable and dependable. They've an working range of -55°C to both a hundred twenty five°C, a hundred seventy five°C, or two hundred°C depending on the connector class. Insert preparations are presented in MIL-STD-1651. The Weald Electronics Ltd Variation is the LMJ series of connectors, that has solder contacts. These merchandise are thoroughly stocked and dispersed by FC Lane Electronics Ltd.


This typical, MIL-DTL-24308 (formerly often 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-detachable), or crimp (removable) float-mounting or rigid mounting brackets. They have got an working temperature choice of -55°C to a hundred twenty five°C.

These are often called D-Subminiature or D-sub connectors and they are used in environments the place excess weight and Place really are a thing to consider, even though accommodating a lot of circuits in relation for their dimensions. This is why they are perfect for missiles, plane, and ground assistance systems. Aside from rack and panel apps, these can be adapted to be used by utilising integral clamps and various relevant accessories.

They may be designed for use in navy programs as follows: classes G and N are for use inside environments on the operating choice of -fifty five°C to one hundred twenty five°C (class N are used in environments exactly where residual magnetism really should be held at lower stages), course H are used when pressures/vacuums must be managed inside the bins/vessels onto which the connectors are mounted, and courses D, K, and M are supposed for use in higher-reliability space applications. FC Lane Electronics Ltd extensively stocks and distributes goods from Positronic Industries that covers the two the MIL specification and business versions of the kind of connector.


Formerly identified as MIL-C-83513, the MIL-DTL-83513 specification describes micro-miniature, polarised shell rectangular connectors which have solder or non-removable crimp contacts. They are really hard-wearing and long lasting and as a result are supposed for use in harsh environments, obtaining substantial dielectric power, significant present-day capability, minimal Call resistance, and superior resistance to vibration and shock. They're light-weight, of smaller dimensions, and also have a superior density of pins.

They are also known as Micro-D connectors and because of their compact dimensions and body weight, are generally used in radars, shoulder-launched weapons, navy GPS, healthcare gear, satellites, drilling equipment, Innovative soldier technology, and aerospace avionics apps.


The common that designers motivation when an software needs small usage of Room and bodyweight with no sacrifice while in the general performance. Other demands of MIL-DTL-28748 include using high-excellent components, a high resistance to shock and vibration, positive locking and an extended life. This specification is often Utilized in aerospace, instrumentation and For several types of portable gear. Previously regarded simply just as M28748, superior density and normal density MIL-DTL-28748 products ranges are created up of rectangular rack and panel connectors with non-removable solder contacts and detachable crimp contacts.
