The MIL-DTL-5015 specification covers the general requirements for circular, electrical connectors with solder or
removable crimp contacts (front and rear release). These connectors offer a unique combination of ruggedness,
durability, and corrosion resistance, making them suitable for use in a wide range of military and industrial
applications — especially those that are exposed to harsh environmental conditions where extreme temperatures
and caustic chemicals may be a concern (e.g., aerospace, oil and gas, salt water, petrochemical, and mining
MIL-DTL-5015 connectors are available in a variety of construction types, including stainless steel or aluminum
shells. It is important to note that the life span (in hours) for resistance to salt spray depends on the plating
material. The connectors also feature large profile knurlings to allow for better handling, along with anti-
decoupling springs, which significantly reduce maintenance requirements. There are several different shell styles:
straight plug, 90° plug, wall mounting receptacle, box mounting receptacle, and cable connecting plug.
Some other notable features and benefits offered by these connectors include a captive coupling nut mechanism
that prevents inadvertent disassembly, multiple interlock systems, positive control of dielectric separation, and
redundant rear wire seals and shell seal inserts to ensure protection from the outside environment.
Other applications where MIL-DTL-5015 connectors may be used include process equipment, telecommunication
systems, generators, machining tools, military ground vehicles, and earth-moving equipment.
