■Features
1. 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
High contact reliability - effective mating length 0.45mm
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 : 1.5mm, 2.0mm, 2.5mm,
3.0mm, 3.5mm, and 4.0mm.
∼
3. 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.

4. Excellent self-aligning range
The use of guide ribs allows 0.33mm of self-
alignment 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.
6. Solder wicking prevention
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
Environment friendly and does not use RoHS
specified prohibited materials.
All materials and substances used to produce these
parts comply with the RoHS standards.

9. High speed signal with noise prevention
The shielded type can support high speed signal
transmissions with noise prevention.
In cases where the application will demand a high level of reliability, such as automotive,
please contact a company representative for further information.
