1.27mm Pitch 2 Piece Low Profile Connector / Flexible Stack Type !!

The 89 Series of low-profile, half-pitch connectors utilizes the concept of securely-fit, one-point contacts. Having the most compact design and lowest profile of all KEL half-pitch connectors, and also featuring a guide mechanism, this product is ideal for SMT applications. The 8903N-FS Series comprises flexible-stack type connectors with the same shape and dimensions of those of the 8903 Series. That series – having gained an excellent reputation in practical situations – provided the basic design of the 8903N-FS connectors; accordingly, the 8903N-FS connectors can be coupled as is to those connectors compatible with the 8903 Series (i.e., 8913-XXX-178SX-X, 8913-XXX-178MSX-A, 8930E-XXX-178MS, and 8931E-XXX-178X). Standard parts offer stacking heights of 20, 22, 24, 26, 28, and 30 mm; however, KEL can also provide connectors with other heights between 20 and 32 mm.
