Amphenol Heavy Duty Cylindrical Connectors 12-052-9 Amphenol 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. Amphenol heavy duty connectors have been exposed to the following environmental conditions, without compromise of mechanical integrity or degradation of electrical performance.
