connector width, yet still retains a sufficient
vacuum area for easy pick-and-place mounting
Minimum width: 3.38 mm
2. Multiple stack height options
In addition to its space saving design, several
stack heights are available and add versatility to
any application. Stack heights: 1.5 mm, 2.0 mm,
2.5 mm, 3.0 mm, 3.5 mm, and 4.0 mm.

Space saving
3. High contact reliability
Despite its small stature and low profile, the contacts
deliver strong contact forces and an effective mating
length of 0.45 mm on the 1.5 mm 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.
4. Excellent self-aligning range
The use of guide ribs allows 0.33 mm of selfalignment on this connector.
5. Reinforced structure with shock absorbing ribs
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.
7. Contamination resistant design
When mated, the connector’s design covers the
contacts which help to keep dust and other debris away
from the contacts. The SMT leads are kept very close
to the connector housing which also helps to prevent
shorts caused by debris on the exposed contacts
8. RoHS compliant
9. High speed signal with noise prevention
