■Features
1. Full Lock Function Added
The inner lock system adopts a full lock mechanism.
This mechanism prevents disengagement to occur due to
an unexpected external shock. (Refer to photo 1)

2. Increase in Crimping Contact Fixation Force and
Semi-insertion Prevention
The double lock is activated for the use method to give a
stress to the cable, to increase crimping contact fixation
force, and to prevent the semi-insertion of the crimping
contact. (Refer to photo 2)
3. Mold Lance Adopted
Since the contact lance may be deformed involving in the
contact after the crimping process, the mold lance has been
adopted.
4. Mis-insertion Prevention
Equipped with the mechanism to completely prevent reverse
insertion and insertion between dissimilar contacts.
8. Various Applications
Photo 2
5. Means to Prevent Solder Crack
The glass enforcement resin is adopted for the pin header to
prevent a solder crack to occur due to heat compression.
With the same series, various applications can
be used for the board solder dip type and in-
line.
9. Listed by UL, C-UL
6. Correspond to Potting
Corresponding to potting, the pin header is provided for
product variations.
Corresponding to potting up to 8mm and mounting height
19.8mm (no retainer), the low profile is achieved.
■
Applications
Electronic equipment, office machines,
industrial equipment, and consumer
equipment, and so on
7. Production Facility Cost Reduction
The female crimping contact uses the DF1B series crimping
contact, which has been conventionally marketed.
Investment for new facilities isn't needed. However, if the
retainer is installed in the cable with AWG#22 or more wire,
use the DF1E crimping contact. The female crimping
contact for in-line is used together with the DF1B applicator.
Therefore, no investment is needed for new facilities.
