1.1mm Pitch Low Profile Compression Connectors
DF26 Series
NEW
2003.7
s
Features
1. Low Profile
Connectors are available in heights : 1.2mm and
1.7mm.
2. Miniature, Space-Saving Design
The space-saving design of these connectors permits
increase in the mounting density as compared to
equivalent products.
3. One-Piece Connector
These connectors support cost reduction requirement
since there is no need for a mating half connector.
This design also permits a reduction in the number of
assembly steps.

Precautions for Use
s
Excessive twisting when mating/un-mating may cause damage to the connector.
s
The contacts are of an exposed design and touching them with bare hands may cause breakdown
of the elements due to contact faults or static electricity.
Manual soldering: 290
10
for 3 seconds
0.15mm
Maximum of 0.03mm at the connector center, with both ends of the connector as reference points.
Refer to "Nylon connector Use Handbook".
Note1: Up to 2 cycles of reflow soldering are possible under the same conditions, provided that there is a
return to normal temperature between the first and second cycle.
Note2: The temperature profile indicates the board surface temperature at the point of contacts with the
connector terminals (for surface mounted receptacle).
