The DF40C(2.0)-70DS-0.4V(51) is a 70-position 2-row 0.4mm female unshielded Stacking Board Receptacle with gold plated phosphor bronze contacts and a black LCP insulator. The DF40 series connector has 2mm stacking height, SMT mounting style and straight connector orientation. Space saving design has minimum connector width, yet still remains a sufficient vacuum area for easy pick-and-place 3.38mm mounting minimum width. The use of guide ribs allows 0.33mm of self-alignment on this connector. Both sides of the connector have been reinforced with the addition of shock absorption ribs. Nickel plated barriers were added to protect the contact areas from potential solder wicking.
