MIL-DTL-22992 - QWL

Amphenol® QWL Series Connectors are tailor made for compact, heavy duty industrial use. The outstanding performance of this series makes it well suited for ship- board installations and ground sup- port power distribution applications where physical strength and depend- ability are key requirements. The QWL Series are a versatile, economical alternative to military qualified designs. Equivalent MS shell sizes and insert arrangements offer compatibility with all standard cable types. MIL-C-22992 environmental connector require- ments are used as a per- formance criteria base for this series to assure reliability under the most severe conditions.
The design features of this connec- tor series provide:
• Exceptional Service - high strength aluminum shells with Alu- milite 225* hard anodic finish and shock resistant resilient inserts.
• Foolproof Operation - rugged double stub coupling threads, left hand accessory threads and sim- ple single keyway mating.
• Versatility - both MS and custom insert patterns available for a wide variety of multiconductor cables.
A complete line of accessories is available for use with QWL Series connectors, including cable sealing and clamp adapters, protective cov- ers, flange gaskets and banding clamps.


Amphenol® QWLD Series heavy duty cylindrical connectors provide reliable power and control functions in hostile environments where ordinary connec- tors cannot survive.
Design features of this connector series provide:
• High Durability - water and explosion proof, resistant to abrasion, corrosion, vibration and shock
• Quick, Positive Mating - double stub threads per MIL-STD-1373 for fast cou- pling, easily cleaned
• Selection - over 300 industrial and MS- approved insert patterns available, including coaxial and thermocouple
On the drilling platform in the North Sea, pump and motor generator controls run smoothly, although constantly exposed to salt spray.
At Prudhoe Bay where the nights are six months long, portable lighting systems per- mit operation regardless of temperature plummeting to 50° below zero.
The circus ferris wheel runs continuously despite the fact that it has rained for five days and all power connections are lying in six inches of mud.
These situations are typical of the extreme conditions under which thousands of Amphenol QWLD connectors are operating daily. Outstanding design features that make these cylindricals a necessity for diffi- cult applications include:
• Alumilite 225* hard anodic finish for abrasion and corrosion resistance or conductive cadmium plate
• Resilient inserts for moisture sealing, positive proof against shock and vibration
• Sealing gaskets at every joint for water- proof assembly
• Cable strain relief provided by clamp bar type accessories
• Left hand accessory threads to prevent damage from disconnect torque applied in the wrong direction
• Closed entry socket contact design in solder or replaceable crimp contacts
