Understanding Military Connector Specs

From the connector field, there are lots of technological phrases that may from time to time be difficult to decipher. Military connectors desire by their extremely nature they meet up with the stringent complex criteria at first laid out via the US Division of military connectors Protection.

They as well as their derivatives are generally known as Military Standard, MIL-STD, or MIL-SPEC connectors. In this article, we look at a few of the commonest requirements and expectations and clarify what exactly they imply.


Previously generally known as MIL-C-38999, MIL-DTL-38999 connectors certainly are a number of 4 connectors that happen to be comprised of bayonet, threaded, and Breech Lok coupling mechanisms. They are environmentally resistant connectors that use removable crimp contacts and also have an working number of -sixty five to +two hundred°C.

Collection I connectors are bayonet coupled and possess superior-vibration properties. These are scoop proof and are ideal for major wind and moisture environments. They can be utilised every time a rapid disconnect coupling system is needed.

Series II connectors are bayonet coupled, are non-scoop proof, and have a lower profile, so are utilized when fat or House is restricted, or in low-vibration, high moisture, and strong wind scenarios.

Series III connectors are coupled by A fast screw Tri commence thread, are scoop proof, and are greatest suited to typical mating and unmating apps and can be employed in large temperature, humidity, wind, or vibration environments when made use of with the right add-ons.

Collection IV connectors are coupled by a Breech Lok system, are scoop evidence, lightweight and suited to blind mating applications, they usually even have higher-vibration characteristics. They can be well suited in significant wind and dampness environments when applied with the right accessories. Insert preparations for all collection are delivered in MIL-STD-1560. FC Lane Electronics Ltd is a number one Price Added Distributor to the SOURIAU Connection Systems variations with the MIL-DTL-38999 sequence one and three.


MIL-DTL-26482, Formerly referred to as MIL-C-26482, are bayonet lock connectors, and collection one (solder) and series 2 (crimp) address the necessities for two series of miniature, fast disconnect, atmosphere resisting, round electrical connectors as well as their equipment. Both equally series include things like hermetic receptacles and they are intermateable when utilized with regular contacts and non-intermateable when utilized with shielded contacts.

The categories and classes of connector consist of lessons E, F, J, and P, which happen to be utilised in environment-resisting circumstances and have an operating array of -fifty five to -125°C. Course H receptacles are suitable for predicaments wherever pressures/vacuums are necessary to be maintained in the containers/vessels which the connector is mounted to.

There are several employs for this connector outside of the Formal armed service specification plus the specification features two circular connector sequence: Sequence I contains MS3110, MS3111, MS3112, MS3114, and MS3116, and Series II incorporates MS3470, MS3474, MS3475, and MS3476 connectors. Insert arrangements are offered in MIL-STD-1669. The Weald Electronics Ltd version is the LMH range of connectors and equipment which are compatible with series one (solder). These solutions are extensively stocked and dispersed by FC Lane Electronics Ltd.


The MIL-DTL-5015 typical, previously often called MIL-C-5015, describes circular connectors that have front and rear launch crimp contacts together with solder contacts. They can be Utilized in electrical electricity, electronic, and control circuits and therefore are extensively used in industrial, civil, and protection purposes as They may be readily available, multipurpose and trusted. They've got an running array of -fifty five°C to both 125°C, one hundred seventy five°C, or two hundred°C dependant upon the connector class. Insert preparations are provided in MIL-STD-1651. The Weald Electronics Ltd version would be the LMJ series of connectors, which has solder contacts. These items are extensively stocked and distributed by FC Lane Electronics Ltd.


This standard, MIL-DTL-24308 (previously 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 an functioning temperature range of -fifty five°C to a hundred twenty five°C.

They're also called D-Subminiature or D-sub connectors and they are used in environments wherever excess weight and space really are a thing to consider, although accommodating lots of circuits in relation to their sizing. For this reason they are perfect for missiles, aircraft, and ground guidance systems. Apart from rack and panel apps, these may also be tailored to be used by utilising integral clamps and various relevant add-ons.

They can be suitable for use in armed forces programs as follows: courses G and N are for use in just environments at the operating selection of -fifty five°C to a hundred twenty five°C (course N are used in environments exactly where residual magnetism has to be held at small concentrations), course H are made use of when pressures/vacuums need to be maintained during the packing containers/vessels onto which the connectors are mounted, and lessons D, K, and M are intended for use in high-trustworthiness House applications. FC Lane Electronics Ltd extensively stocks and distributes items from Positronic Industries that covers the two the MIL specification and commercial variations of this sort of connector.


Previously referred to 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 difficult-sporting and long lasting and therefore are supposed to be used in harsh environments, acquiring superior dielectric energy, superior recent functionality, lower Get hold of resistance, and substantial resistance to vibration and shock. They are light-weight, of little sizing, and also have a significant density of pins.

These are generally known as Micro-D connectors and due to their smaller dimension and fat, are commonly used in radars, shoulder-introduced weapons, military GPS, health care equipment, satellites, drilling instruments, Highly developed soldier technological know-how, and aerospace avionics applications.


The typical that designers desire when an software needs minimal usage of Area and body weight with none sacrifice in the efficiency. Other specifications of MIL-DTL-28748 involve using substantial-top quality supplies, a substantial resistance to shock and vibration, optimistic locking and an extended lifetime. This specification is typically Utilized in aerospace, instrumentation and For most sorts of moveable machines. Beforehand known merely as M28748, superior density and typical density MIL-DTL-28748 merchandise ranges are made up of rectangular rack and panel connectors with non-detachable solder contacts and removable crimp contacts.
