Circular Connectors - Mil-Spec, Micro-Miniature, Filter, Sealed, and Custom
MIL-SPEC Connector Derivatives
Amphenol doesn’t just offer connectors within standard MIL-SPEC boundaries; customization beyond MIL-SPEC standards to craft any interconnect solution to meet your unique needs is available through our 38999 Plus catalog.
Whether it’s signal connectors, power connectors, hybrid or high-speed connectors, 38999 Plus presents a massive inventory of MIL-SPEC styles and options to overcome any interconnect challenges.
Choosing the Right Connector

38999 Plus offers a lot of interconnect options within and outside of MIL-SPEC standards. When choosing the right circular connector for your application, there are a couple of factors you should consider.
What Kind of Environment?
The environment where the connector will be used is paramount. Factors such as temperature extremes, exposure to moisture, dust, chemicals, and vibration can all impact connector performance and system integrity. Ensuring the connector has proper sealing, corrosion resistance, and durability against the elements is critical for reliable operation.
What is the Termination Method?
The termination method refers to how the connector is attached to the cable or wire. Common methods include crimping and soldering. Choosing the right termination method will depend on a host of factors, including what kind of application the connector is being used for, ease of installation, time, reliability, and the type of connector itself. Whichever method is chosen, developers must ensure it allows for a secure and efficient connection that meets the application’s requirements.
What Kind of Contacts, and In What Insert Arrangement?
The type, material, and configuration of contacts within the connector are vital for ensuring effective power and signal. Contacts can be made from various materials, including gold and copper, each offering different levels of conductivity and durability. The arrangement and density of the contacts should match the application's needs, whether it’s for high-speed data transfer, power distribution, or signal integrity.
What Type of Design Fits Best with My Application?
The connector’s design, including its size, shape, and coupling mechanism, must align with your application’s physical constraints and requirements. When assessing the right design for your application you should also consider the connector’s ease of use, such as how quickly and securely the connector can be mated and unmated; its degree of ruggedness and ability to withstand harsh environments, and whether it includes features like keying to prevent misalignment.
38999 Plus Offers Endless Options
This includes, but isn’t limited to:
Options |
|
|---|---|
EMI Filter Connectors |
Our Filter Connectors are optimized for electromagnetic interference (EMI) shielding and radio frequency interference (RFI) shielding and are based on the most popular MIL-SPECs: D38999 Series I, II, III; 26482; 5015; and 2M Micro 38999. We also build Filter Adapters for retrofitting existing systems with EMI/RFI shielding, as well as Transient Voltage Suppression (TVS) Diode Connectors and Metal Oxide Varistor (MOV) Connectors for protection against EMP and transient voltage events |
Hermetic Connectors |
Our Hermetic and Sealed Connectors are available in the same MIL-SPECs, with numerous QPL versions. Amphenol hermetically sealed connectors feature glass or epoxy seals, offering superior leak-rate performance in a ruggedized package.
Both Filter, Hermetic, and Sealed Connectors come with various customization options, including special shell geometries, printed circuit board (PCB) contacts, and high-speed contacts. |
Miniature and Micro-Miniature Connectors |
Our collection of Miniature and Micro-Miniature Circular Connectors includes the 2M Micro 38999 series, which delivers the performance of a D38999 Series III connector but in a more compact and lighter form. We also offer the Bantam Micro-Bayonet Series, an economical and lightweight option for general-purpose use in commercial aerospace. Our miniature and micro-miniature solutions also include the Multi-Media Ruggedized (MRC) connectors and the Warrior Grip Series, which is specifically designed for soldier-worn systems, including the U.S. Army's Nett Warrior system. |
High Power Options |
Amphenol’s High Power and High Voltage Connectors and Contacts are capable of handling higher currents and voltages for applications that demand extensive power distribution. |
Waterproof Connectors |
Our Aquacon High Pressure Immersible Connectors are thoroughly sealed against water ingress and incorporate 316 stainless steel shells for corrosion resistance. With the ability to withstand 1500 PSI, Aquacon provides a secure waterproof connection for applications facing extensive fluid immersion or hazardous deep ocean environments. Also available in a hermetic option for an airtight seal that provides extra protection. |
Quick Disconnect Connectors |
Our D38999 Breakaway Fail-Safe Connectors feature a highly durable, lightweight non-metallic lanyard designed to enable rapid quick disconnection. Many other Amphenol connectors such as our 2M Micro-Miniature Series and Push-Pull Connectors incorporate quick disconnect features. |
Dualok High-Vibration Connectors |
Our Dualok High Vibration Connectors are enhanced for severe high-vibration environments and exceed MIL-DTL-38999 Series III vibration resistance. |
Bulkhead Feedthrough Connectors |
Our bulkhead feedthrough connectors simplify installations by eliminating discrete wire termination and achieving a secure and reliable power or signal connection through a bulkhead or panel. Also available in a fiber-optic connector configuration. |
BACC63 and EN2997 Connectors |
Our MIL-SPEC portfolio features connectors that meet Boeing BACC63 and European EN2997 specifications. |
Jam Nut Connectors |
Our Jam Nut connectors allow you to save space and weight in your PCB applications due to a reduced flange design, which has a smaller profile than standard jam nut receptacles. |
Extensive Contact Options |
Our MIL-SPEC connectors utilize our complete line of crimp, solder, printed circuit tail (PC tail), printed circuit board (PCB), and compliant pin contacts from size 0 to size 22D. |
Connector Savers |
Protect your connectors from the wear and tear of repeated mating and extend their service life with our 38999 Connector Savers. |
RoHS-Compliant Plating |
Environmentally friendly, cadmium-free plating finishes that meet ROHS compliance include gold, electroless nickel, stainless steel, black zinc nickel, our new AP-93 plating, and more. |
Accessories and Custom Options |
We carry a large selection of Accessories and Custom Options for our entire catalog of circular connectors including 38999 integral accessory features, backshells, strain reliefs, caps, and dummy receptacles. |
