Amphenol Aerospace Heavy Duty Class L Commercial MIL-DTL-22992 Connectors

Amphenol Aerospace Heavy Duty Class L Commercial MIL-DTL-22992 Connectors

Amphenol Aerospace Heavy Duty Class L Commercial MIL-DTL-22992 Connectors are offered as a lower-cost, commercial version of the heavy duty power connectors critical for rugged environmental conditions. These connectors feature MIL-DTL-22992 Class L insert arrangements and an arc quenching design to protect users and equipment if connectors are inadvertently disconnected under load. A programmed coupling sequence ensure grounding and neutral contacts engage before power contacts. Constructed using a high strength aluminum and an unique combination of grommets and seals, these rugged connectors provide waterproofing in any condition - mated or unmated, capped or uncapped.

Design Features
  • Greatest Capacity - Current ranges 40 to 200 amps, conductor sizes 6 to 4/0
  • Safety - Complete protection even if connectors are inadvertently disconnected under load
  • Foolproof Mating - Design incorporates voltage, current, frequency, phase and grounding requirements
  • Standardization - MIL-DTL-22992 Class L insert arrangements for maximum reliability
  • Serviceable Contacts - Contacts are normally crimped to the cable before connector assembly. No insertion tools required. Bushings are available to adapt smaller diameter wires to larger contacts
  • Arc Quenching Design - Recessed socket contacts within the insert create an arc suppressing chamber which protects the user when connectors are separated under load
  • Programmed Coupling Sequence - Grounding and neutral contacts engage before power contacts
  • Waterproof Design - A unique combination of grommets and seals provides waterproofing in any condition - mated or unmated, capped or uncapped
  • Straight-line attachment of accessories eliminates possibility of cable twisting or misalignment
