Key Features of
MIL Circular Connectors

An MIL circular connector, also known as a circular MIL-SPEC connector, is a rugged, high-reliability electrical connector designed for aerospace and industrial use. These connectors follow strict MIL-SPEC standards, so they can withstand shock, vibration, moisture, and extreme temperatures while maintaining a secure and uninterrupted electrical connection.

FAQ’s

Custom Wire Harness Manufacturer

What are the common MIL-SPEC standards for circular connectors?

MIL circular connectors follow various standards, including:

  • MIL-DTL-5015: General-purpose power and signal connectors
  • MIL-DTL-38999: High-performance aerospace and industrial applications
  • MIL-DTL-26482: Compact, environmentally sealed connectors
  • MIL-DTL-83723: Hybrid connectors for extreme conditions

MIL circular connectors are designed with high-quality, durable materials to withstand extreme environments. They typically consist of the following components:

  • Shell: The outer casing, made from aluminum, stainless steel, or composite materials, provides corrosion resistance and mechanical protection
  • Contacts: Precision-machined gold-plated or silver-plated copper alloy contacts maintain low electrical resistance and long-term conductivity
  • Insulator/Dielectric: A non-conductive material (such as PTFE or thermoplastic) that separates and supports the electrical contacts
  • Coupling Mechanism: Secure locking options, including bayonet, threaded, or push-pull couplings, for a tight and vibration-resistant connection
  • Sealing Gaskets & O-Rings: Provide environmental sealing (IP67/IP68 rated) to protect against dust, moisture, and chemical exposure
  • EMI/RFI Shielding: Metal-plated housings and shielded cables help minimize EMI and RFI for reliable signal integrity
