The YL series circular connector is strictly built to GJB598A-1996 Series I specifications, the Chinese equivalent to MIL-C-26482G Series I specifications.

Available with bayonet coupling mechanism and solder contacts, the YL series circular connector allows fast engagement and disengagement. Housed in the compact design are densely arranged connector pins. Known for its ability to withstand various environmental challenges, the male connector delivers exceptional reliability which suits itself for demanding military jobs such as providing electrical connection for the fighter aircraft, missile and fleet.
