Amphenol Heavy Duty
Cylindrical Connectors
MIL-C-22992/Proprietary
• High Current Capacity
• Rugged Construction
• Safety
• Serviceability
Amphenol meets the demands for heavy duty connectors by
providing three cylindrical connector series, each with unique
design characteristics for reliable operation in specific indus-
trial environments.
Class “L” –
for the heaviest electrical loads (Pages 2 – 19)
• Current range from 40 to 200 amperes
• Direct current or single/three phase, 60/400 Hertz alternat-
ing current
• Automatic grounding for safety
• MIL-C-22992 qualification
QWLD –
for most power and control circuits (Pages 21 – 77)
• Military (MIL-C-22992) qualified connectors and industrial
equivalents available
• Increased shell size for greater durability than similar stan-
dard connectors
QWL –
a more compact heavy duty design for industrial power and control applications
(Page 78, references Amphenol Catalog 12-053)
These three series share the following common characteristics which are critical to reliable heavy
duty connectors:
• Resistance to the operating environment. Refer to environmental data, below.
• Double stub coupling threads for faster connections; no cross threading, easy cleaning.
• Left hand accessory threads to minimize cable twisting, wire breakage, accidental connector
disassembly.
• Gaskets or O-rings at appropriate surfaces for perfect weathertight connections.
