Compliant with GJB2446 (equivalent to MIL-C-83513) standards, it can be interchanged with the MDM series products of the United States. The contact spacing is 1.27mm. It adopts gold-plated twisted wire type elastic pins (twisted needles). Each contact has up to 7 contact points. There are eleven specifications: 9, 15, 21, 25, 31, 37, 51, 66, 74, 100, and 144 cores. The crimped products are applicable to the wire core cross-sectional area of 0.035mm² to 0.20mm². It is best to choose 0.1mm² to 0.15mm². It has the characteristics of direct insertion connection, high density, light weight, miniaturization, etc. It can be used for connections inside and outside the equipment, between PCB boards, between cables and PCB boards, and between cables. It is often used in unmanned aerial vehicle missions, flight control, and mechanical-electrical system signal connections.
