Comparing Military Style Connector Specifications

The electrical connector you choose to power your applications depends on many factors including its specifications, intended use and the environment in which it will be operating. Finding the right one for your needs and budget can take time, especially with all the options available.

Thanks to a strong crossover between military technology and commercial innovation, there is an abundance of military-style connector options to meet the most stringent requirements and withstand the harshest conditions.

The electrical connectors that are known today as Military Standard (or MIL-SPEC) can be traced back to the 1930s, when the U.S. Department of Defense began developing new military and aerospace electronics. Over the decades, demand for these durable and reliable components grew – particularly in industries like construction, automotive, agriculture and medical technology.

That’s when commercial drop-in equivalents for circular mil-spec connectors took off as a more affordable option. These connectors meet the same standardization specifications of the U.S. Department of Defense and are tested to endure the extreme environments faced in the military.

In this mil-spec connectors guide, we’ll cover what some of these specifications mean and which of Amerline's drop-in equivalents align.

MIL-DTL-5015: Heavy Duty Circular Connectors

The MIL-DTL-5015 specification covers circular threaded electrical solder and crimp style contact connectors.

They are versatile, with a wide range of use by both the military and commercial industries.

Amerline’s AEC 5015 series is designed, manufactured and thoroughly tested to key requirements of the Mil 5015 Series. This means it meets temperature, vibration, shock, salt spray, humidity, insulation and other specifications.

The different AEC 5015 classes come with a variety of shell styles, insulation and contact options. Designs include wall mounting receptacles, box mounting receptacles, straight plugs and angled plugs, among others. Custom design options are also available.

The AEC 5015 series is often used in applications like:

  • Military vehicles
  • Earthmoving equipment
  • Communication equipment
  • Industrial machinery
  • Traffic signals
  • High current systems
  • Factory automation
  • Robot control
  • Power generators
  • Medical equipment
  • Shipbuilding equipment

VG 95234: Ruggedized Power and Signal Connectors

Connectors designed in accordance with the VG 95234 specification are known for being highly reliable and are often used for tactical ground vehicle applications.

The AEC 95234 Series are circular reverse-bayonet connectors that are drop-in equivalents to VG 95234 Series connectors. The connectors are interchangeable with 5015 Series connectors. Although the two have the same shell dimensions and contact layouts, they have different coupling systems.

These AEC 95234 connectors offer remarkable protection against vibration. The reverse bayonet coupling design also makes for easy connection and disconnection.

Some of the most common uses of the AEC 95234 connectors include:

  • Mass transportation
  • Military tactical ground vehicles
  • Power generators
  • Earthmoving and mining equipment
  • Commercial land and sea transportation
  • Communication equipment
  • Entertainment lighting
  • General industrial equipment

MIL-DTL-26482: High-Performance Environmental Miniature Connectors

MIL-DTL-26482 connectors use a quick disconnect bayonet coupling for rapid positive mating and unmating. They are especially popular when a small, environmentally-resistant circular signal connector is needed.

Amerline’s AEC 26482 Series are intermateable and interchangeable with other 26482 Series I connectors.

Connectors in this commercial series are environmentally-resistant miniature circular connectors. They come with a rugged shell, a resilient insulator and grommet, and current-carrying capacities. These connectors will operate in harsh conditions, including temperatures between -55°C to +125°C (-67°F to +257°F).

AEC 26482 connectors are commonly used for applications like:

  • Automation
  • Sensors
  • Measuring equipment
  • Machine tools
  • Communication equipment
  • Mobile equipment
  • Telecommunications
  • Power generators
  • Engines
  • Industrial machinery
  • Commercial and military aviation
  • Aerospace

MIL-DTL-22992: Heavy Duty High Power Connectors

Amerline’s AEC 22992 Commercial Series are designed to meet the demands of heavy power interconnections, making them highly suitable for both industrial and military applications. Thanks to the high-strength aluminum, the heavy-duty AEC 22992 connectors can withstand the high impact of harsh environments.

AEC 22992 connectors are commonly used for:

  • Military ground vehicles / mobile facilities
  • Geophysical / heavy equipment
  • Power distribution systems
