High density mounting: Space saving design that has a minimum connector width, yet still retains a sufficient vacuum area for easy pick-and-place mounting; Minimum width : 3.38mm.Multiple stack height options: In addition to its space saving design, several stack heights are available and add versatility to any application. Stack heights : 1.5mm, 2.0mm, 2.5mm,3.0mm, 3.5mm, and 4.0mm.High contact reliability: 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.Excellent self-aligning range The use of guide ribs allows 0.33mm of selfalignment on this connector.Reinforced structure with shock absorbing ribs: Both sides of the connector have been reinforced with the addition of shock absorbing ribs.Solder wicking prevention: Nickel-plated barriers were added to protect the contact areas from potential solder wicking.Contamination resistant design: When mated, the connector 's design covers the contacts which help to keep dust and other debris from the contacts. The leads are kept very close to the connector housing which also helps to prevent shorts caused by debris on the exposed contacts.High speed signal with noise prevention: The shielded type can support high speed signaltransmissions with noise prevention.Type: BColour: blackMaterial: metal + plasticPackage Contents:1 * Suitable for Raspberry Pi computing module Compute module 4 CM4 socket DF40C-100DS-0.4vOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
