MIL-DTL-5015
MIL-DTL-5015 is a
Many manufacturers have created connectors based on MIL-DTL-5015 and MIL-C-5015, for example Radiall-Van System. These connectors are available as off-the-shelf products for end users, as well as "mil-COTS" products for railway and military use.
History
In the early 1930s,
In May 2000, MIL-C-5015G was superseded by MIL-DTL-5015H, six years after its publication.[7]
In December 2009, MIL-DTL-5015 was superseded by SAE-AS50151,[7][3] pursuant to the general United States Department of Defense goal to reduce the number of military standards in favor of industry technical standards supported by standards organizations.[8] Whilst the original military standard is no longer in use officially, the family of connectors continues to be called MIL-DTL-5015 or MIL-C-5015 by manufacturers and users.
Applications
MIL-DTL-5015 connectors are used for many situations where mechanical and electrical reliability is important. This includes civil applications (aerospace, oil and gas, salt water, petrochemical, mining, earthmoving, telecommunication, generators, machining tools, rail), as well as military applications (communications, aircraft, ground vehicles).[9]
Physical specifications
The main advantages of MIL-DTL-5015 connectors are as follows:[10][9]
- Ease of engagement and disengagement
- Compatibility different types and numbers of contacts, allowing power and signal lines in one connector
- Wide range of allowable contact voltages and currents (up to 225 A for Series I)
- Rugged mechanical performance under harsh environmental conditions
- Variety of materials and finishes (stainless steel, aluminum, zinc)
- Wide temperature range of –55 °C up to 200 °C, depending upon the class of the connector[11]
- Resistance to vibration and mechanical shock (anti-decoupling springs)
- Relatively low price
- Interlock and captive nut to prevent inadvertent disassembly
- Several shell styles (straight, right angle, wall receptacle, box receptacle, cable plug)
One significant drawback is the inefficient use of panel surface area when used in arrays, compared to rectangular connector housings. The fine thread is also prone to mechanical damage and can be time-consuming to tighten.[12]
Another disadvantage to MIL-DTL-5015 connectors is that they have only one keyway,[13] unlike some later connector specifications, such as MIL-DTL-38999. This limits the connectors' ability to be polarized to prevent mis-mating of same-shell-size connectors in an area where multiple sets of plugs and receptacles exist. Limited polarization is available in certain insert configurations, which relies on the pins bottoming out on the opposing connector face to prevent engagement. Connectors with multiple keyways can be polarized so that the shells prevent engagement of the pins on mis-mated connectors entirely.
There are 19 shell sizes (specified as size 08 through 40) with about 160 approved insert arrangements incorporating 1-85 contacts.[13][14] The circular connectors are available with a choice of wall mount, box mount, cable connecting and jam-nut receptacles, as well as standard or self-locking plugs.[15]
MIL-C-5015 specifies four discrete product categories known as series. Connectors from each of the first three series are compatible, however, their individual components differ:[12]
Series | Category | Standard military PIN | Corresponding SAE standard |
---|---|---|---|
I | Solder contact connectors | MS3100[10] | SAE-AS31001B |
II | Front release, crimp contact connectors | MS3400[16][17] | SAE-AS39029/44D |
III | Rear release, crimp contact connectors | MS3450[12] | SAE-AS39029/29C |
IV | Connector accessories | (various)[18] | SAE-AS85049/31B |
It also refers to classes of connectors, which specify products in more detail:[7]
Class | Crimp contacts | Solder contacts | Features |
---|---|---|---|
A | No | Yes | Solid shell |
B | No | Yes | Split shell |
C | No | Yes | For pressurized equipment |
D | Yes | Yes | For high-impact conditions |
DJ | Yes | Yes | For high-impact conditions; with backshell |
E | No | Yes | Environment resistant |
F | No | Yes | Environment resistant; with clamp |
H | No | Yes | Hermetically sealed |
K | Yes | Yes | For firewalls |
L | Yes | No | Fluid resistant |
P | Yes | No | Environment resistant; potted solder contacts |
R | Yes | Yes | Grommet-sealed without clamp |
U | Yes | No | Fluid resistant |
W | Yes | No | General purpose |
Commercial products
Several manufacturers have created derivative circular connectors that intermate with the military versions designed to MIL-C-5015 and/or MIL-DTL-5015. Commercial variants and military-style connectors are sometimes called Type AN connectors, MS connectors, or Amphenol connectors.
Similar connectors with different contact arrangements and bayonet coupling rings are also available to military specifications.[19] A wide range of MIL-DTL-5015 connectors are available on the market, with specifications and drawings commonly supplied.[20]
