Product Overview

The DF40 series Board-to-Board and Board-to-FPC Connector with space saving design that has a minimum connector width, yet still retains a sufficient vacuum area for easy pick-and-place mounting. In addition to its space saving design, several stack heights are available and add versatility to any application. Stack heights - 1.5, 2, 2.5, 3, 3.5 and 4mm. Despite its small stature and low profile, the contacts deliver strong contact forces and an effective mating length of 0.45mm on the 1.5mm stacking height. This connector utilizes a locking system that prevents accidental unmating issues and emits a clear tactile click to ensure that mating has been completed. 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 absorbing ribs. Nickel-plated barriers were added to protect the contact areas from potential solder wicking.
  • High density mounting
  • Multiple stack height options
  • High contact reliability
  • Reinforced structure with shock absorbing ribs
  • Solder wicking prevention
  • Contamination resistant design
  • High speed signal with noise prevention
  • Minimum Width: 3.38mm




The contacts in each of the 4 corners serve as metal solder brackets only and should NOT be used for current carrying.
