Top and Bottom Entry

Entry in One Connector

The new 44812 series Low Profile PC Board Connector is a significant step forward in updating the

KK product line to reflect customer’s needs in the 21st century. Utilizing terminal design features

from the SPOX™ family, Molex has been able to improve performance while shrinking the overall

package. The new design functions as both a top and bottom entry version, and retrofits into

existing KK .100” Pitch bottom entry PCB layouts. Overall connector height has been reduced by

almost 50%! The housing is made out of high temperature nylon for surface mount compatibility.

The new design also permits higher current ratings and a higher operating temperature.
