Mil-Spec Circular Connector Reference

MIL-DTL-26482 Connectors

MIL-DTL-26482 covers miniature, quick-disconnect circular connectors used when teams need sealed bayonet-style plugs and receptacles without jumping to the density or cost of MIL-DTL-38999.

What MIL-DTL-26482 Covers

MIL-DTL-26482 is a miniature circular connector specification for environment-resisting quick-disconnect plugs and receptacles. It is common in instrumentation, industrial controls, aerospace support equipment, vehicles, and other harnesses that need a compact metal circular connector.

Series I covers the older solder-contact and front-release styles. Series II is the later bayonet family with rear-release crimp contacts and is often the better fit for serviceable harness assemblies.

The main quote inputs are shell size, insert arrangement, series, shell style, contact gender, wire gauge, backshell or strain relief, sealing requirements, labels, and test scope.

MiniProto RoleBuilt Assembly
OEM pages from Amphenol, Glenair, and similar manufacturers sell connector parts. MiniProto turns the selected plug, receptacle, contacts, backshells, wire, labels, and test requirements into a built harness assembly with prototype-friendly ordering.

Prototype-Friendly Assembly

Parts are only half the job.

MiniProto is set up for low-volume and prototype harnesses: connector sourcing, wire cutting, labeling, crimping, continuity checks, and IPC/WHMA-A-620 workmanship inspection practices. Typical lead time depends on connector availability and assembly scope.

No MOQ

Good fit for one-off prototypes, test fixtures, and pilot builds that still need a real circular connector.

Crimp Process

Series II builds can be crimped, inserted, pull-checked, labeled, and continuity-tested as a harness.

Inspection

Workmanship checks can follow IPC/WHMA-A-620 workmanship practices for strip length, crimp quality, strain relief, and routing.

Sourcing

We quote against live availability for the shell, contacts, backshell, finish, and mating half instead of assuming catalog stock.

Series And Variant Choices

Series ILegacy

Older miniature circular family with solder and front-release variants. It can be appropriate for drawings that already specify MS311x-style parts.

Series IIRear Release

Bayonet-coupled crimp-contact family with rear-release contacts. Usually easier to service and more practical for harness production.

HermeticPanel Seal

Hermetic receptacles are used when pressure containment across a wall or panel matters. They change sourcing, cost, and assembly assumptions.

Cost Drivers

SeriesMedium

Series II crimp parts may cost more than simple solder builds but reduce service labor and rework risk.

Contact CountMedium

Dense size-20 layouts increase stripping, crimping, insertion, inspection, and continuity-test time.

AccessoriesHigh

Backshells, cable clamps, environmental boots, and shield termination often dominate the practical assembly cost.

Common Questions

What is a MIL-DTL-26482 connector?+

It is a miniature, environment-resisting circular connector specification covering quick-disconnect plugs, receptacles, accessories, and hermetic receptacles.

What is the difference between MIL-DTL-26482 Series I and Series II?+

Series I is the older family with solder and front-release styles. Series II is the later bayonet crimp-contact family with rear-release removable contacts.

What shell sizes are common for MIL-DTL-26482?+

Common catalog shell sizes run from 8 through 24, paired with insert arrangement codes such as 10-6, 14-19, or 20-41.

Are MIL-DTL-26482 connectors the same as MIL-DTL-38999?+

No. Both are circular mil-spec connector families, but 38999 is a higher-density severe-environment family with different series, shell geometry, and insert standards.

Can Series I and Series II MIL-DTL-26482 connectors mate?+

Power-contact versions are generally described as intermateable when the correct arrangement and gender are selected, but shielded-contact variants and exact part details must be checked.

What contacts do MIL-DTL-26482 connectors use?+

The family includes solder-contact and crimp-contact options depending on series and part type. Series II rear-release crimp contacts are common for serviceable harnesses.

Is MIL-DTL-26482 waterproof?+

The spec is environment-resisting, but sealing depends on the exact class, plug and receptacle pair, backshell, wire seals, unused cavities, and assembly quality.

When should I choose MIL-DTL-26482?+

Choose it when you need a compact metal circular connector with bayonet coupling and moderate density, but do not need the highest-density 38999 package.
