Being aware of Military Connector Specs

Being familiar with Military Connector Specifications™

In the connector field, there are several complex phrases that may often be hard to decipher. Military connectors demand by their extremely character they meet up with the stringent technical benchmarks initially laid out because of the US Division of Defense.

They as well as their derivatives are commonly often called Military mil-dtl-28748 connectors Normal, MIL-STD, or MIL-SPEC connectors. In this article, we glance at many of the most typical specs and requirements and clarify what precisely they necessarily mean.


Earlier often called MIL-C-38999, MIL-DTL-38999 connectors really are a number of four connectors which happen to be comprised of bayonet, threaded, and Breech Lok coupling mechanisms. They can be environmentally resistant connectors that use detachable crimp contacts and possess an operating variety of -65 to +200°C.

Sequence I connectors are bayonet coupled and possess higher-vibration Homes. These are scoop proof and are ideal for major wind and moisture environments. They are utilised when a quickly disconnect coupling technique is required.

Sequence II connectors are bayonet coupled, are non-scoop proof, and have a small profile, so are applied when excess weight or Room is limited, or in very low-vibration, superior moisture, and strong wind predicaments.

Collection III connectors are coupled by A fast screw Tri start out thread, are scoop proof, and therefore are very best suited for normal mating and unmating programs and can be used in superior temperature, dampness, wind, or vibration environments when made use of with the proper extras.

Series IV connectors are coupled by a Breech Lok system, are scoop proof, lightweight and suited to blind mating purposes, and they also have substantial-vibration attributes. These are well matched in substantial wind and dampness environments when used with the appropriate add-ons. Insert arrangements for all sequence are offered in MIL-STD-1560. FC Lane Electronics Ltd is a leading Price Added Distributor with the SOURIAU Connection Technologies versions from the MIL-DTL-38999 sequence 1 and 3.


MIL-DTL-26482, Beforehand called MIL-C-26482, are bayonet lock connectors, and sequence one (solder) and collection two (crimp) protect the requirements for 2 number of miniature, rapid disconnect, environment resisting, round electrical connectors and their equipment. Equally sequence consist of hermetic receptacles and they are intermateable when utilised with standard contacts and non-intermateable when employed with shielded contacts.

The categories and courses of connector include things like courses E, F, J, and P, that are utilised in surroundings-resisting predicaments and possess an functioning selection of -fifty five to -a hundred twenty five°C. Class H receptacles are suitable for predicaments where pressures/vacuums are necessary to be preserved in the bins/vessels which the connector is mounted to.

There are plenty of makes use of for this connector outside of the official armed service specification plus the specification involves two circular connector sequence: Collection I contains MS3110, MS3111, MS3112, MS3114, and MS3116, and Sequence II includes MS3470, MS3474, MS3475, and MS3476 connectors. Insert preparations are provided in MIL-STD-1669. The Weald Electronics Ltd Edition could be the LMH array of connectors and accessories that are appropriate with collection one (solder). These goods are thoroughly stocked and distributed by FC Lane Electronics Ltd.


The MIL-DTL-5015 common, Earlier referred to as MIL-C-5015, describes circular connectors which have entrance and rear launch crimp contacts and also solder contacts. These are used in electrical electrical power, Digital, and Handle circuits and so are widely Utilized in industrial, civil, and defense programs as they are readily available, flexible and reliable. They have got an running variety of -55°C to either one hundred twenty five°C, a hundred seventy five°C, or 200°C according to the connector course. Insert preparations are presented in MIL-STD-1651. The Weald Electronics Ltd version is definitely the LMJ number of connectors, which has solder contacts. These products are extensively stocked and dispersed by FC Lane Electronics Ltd.


This normal, 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-detachable), insulation displacement (non-detachable), or crimp (detachable) float-mounting or rigid mounting brackets. They've an operating temperature selection of -55°C to a hundred twenty five°C.

They are also known as D-Subminiature or D-sub connectors and they are Utilized in environments where bodyweight and House can be a thing to consider, whilst accommodating many circuits in relation for their sizing. For that reason they are perfect for missiles, plane, and floor assistance devices. In addition to rack and panel applications, these can even be tailored to be used by utilising integral clamps and various similar extras.

These are made for use in armed service programs as follows: courses G and N are for use within just environments for the running choice of -fifty five°C to a hundred twenty five°C (class N are used in environments in which residual magnetism has to be held at lower stages), course H are made use of when pressures/vacuums need to be managed in the packing containers/vessels on to which the connectors are mounted, and courses D, K, and M are intended for use in large-dependability space programs. FC Lane Electronics Ltd extensively shares and distributes goods from Positronic Industries that addresses each the MIL specification and professional versions of the style of connector.


Beforehand known as MIL-C-83513, the MIL-DTL-83513 specification describes micro-miniature, polarised shell rectangular connectors that have solder or non-detachable crimp contacts. They can be tough-wearing and long-lasting and as such are intended for use in harsh environments, having substantial dielectric toughness, higher present-day capacity, low Speak to resistance, and higher resistance to vibration and shock. They're lightweight, of modest dimension, and also have a significant density of pins.

They are also known as Micro-D connectors and due to their smaller measurement and pounds, are generally Utilized in radars, shoulder-introduced weapons, armed service GPS, medical equipment, satellites, drilling tools, Sophisticated soldier technological innovation, and aerospace avionics applications.


The regular that designers drive when an application demands minimal utilization of space and bodyweight with none sacrifice in the overall performance. Other necessities of MIL-DTL-28748 incorporate using substantial-top quality products, a substantial resistance to shock and vibration, positive locking and a lengthy life. This specification is usually Employed in aerospace, instrumentation and For several kinds of portable equipment. Formerly regarded basically as M28748, high density and normal density MIL-DTL-28748 product or service ranges are made up of rectangular rack and panel connectors with non-removable solder contacts and detachable crimp contacts.
