Primary Connectors

FAA L-823, Styles 3 and 10, Class B

Primary Connectors are available for screened (shielded) and unscreened (unshielded) cable.
All of our Primary Connectors comply with the appropriate FAA 5345-26 requirements for plugs and receptacles (cable connectors).
Efla’s Primary Connectors are packed and delivered in kits including all the necessary parts for making the assembly on primary cables. Each Primary Connector kit contains parts for a pair (a plug and a receptacle), resulting in a watertight post-installation connection.
Nominal rating: 25 A and 5 000V



FOR SCREENED CABLES



KD 500 -series   KDR 600, Resin type
 
Quick installation with conductive parts, screen continuity and insulation parts filled with silicon grease.   Resin-type Primary Connector for heavy-duty use. Efla’s resin type connector is supplied with a high performance PU resin to be poured inside the insulation body around the connective parts and screen continuity.

KD 500 KD 500/YG KD 500/B

Screen continuity

The standard screen continuity is a 2.5 mm² tinned
copper wire, 300 mm long. Upon request, KD 500 and KDR 600 may be supplied with insulated screen continuity in yellow-green (e.g. KD 500/YG) or black (e.g. KDR 600/B). 6 mm² is also available.
