Features
1.Reinforced lock structure with swing lock
A swing-lock structure, featuring our own unique
connection method, reinforces the lock structure of
the electric cable side, with a structure resistant to
tough electric cable routing and disengagement of
cables under load.
In addition, the connection surface has a guide
insertion to facilitate insertability (patented)

2.Header lock improves plug retention
When connecting, the header connector secures the
molded-lance. Play of molded lance is prevented for
added strength. (patented)
3.Highly reliable contact structure
Despite the low-profile design, with a stacking height
of 1.4mm, an effective mating length of 0.42mm is
achieved. The structure features two-point contact
terminal geometry with high contact reliability.

4.Insert guide key prevents misalignment
Insert guide key guides the crimp socket to the
correct mating position and prevents misalignment,
which improves mating operation and prevents
possible connector breakage with incorrect mating.
5.Solder wicking prevention
The integral molding eliminates any gap between the
terminals and case to prevent solder wicking.
Insert guide key touches to
the header prior to the
positive lock, which guides
the socket to the correct
mating position.
6.Case disengagement prevention
Reinforcing hardware (metal fittings) are integrated in
the molding, which help prevent the case from
disengaging with the terminals due to tough electric
cable routing and load.
Starts mating after the socket is aligned to
the correct position
7.Cost effective
Terminals and metal fittings are collectively integrated
into the molding to reduce assembly cost.
