XC7
DIN Sequence Connectors
An improved DIN-standard Sequence
Connector
■ Allows power line to daughter board connection
first and removal last.
■ Used the same way as regular DIN connectors.
Dimensions are those of DIN B-type and C-type
connectors. Mated length is 4 mm. All contacts
are sequential contacts, an improvement on standard connectors.
■ Sockets are equipped with 1-mm long sequential
contacts. Sockets can be stacked up to 2 levels,
and Plugs can be stacked up to 3 levels.
■ Uses a double-sided contact design. Gold/palla-
dium plating has an insertion durability of 5,000
cycles.
Note:
Cannot be mated with XC5 and XC6 Series.
RoHS Compliant

■ Mates with
Standard DIN
Connectors
• Dimensions are the same as those of
standard DIN connectors XC5.
• The sequential contacts on the Socket
and Plug are 1 mm long, so they cannot
be interchanged with DIN Connectors.
Use as a Socket/Plug pair.
■ Precautions
Correct Use
Automated soldering
Dimensions after Mounting
Use masking tape to mask the Right-angle
Connectors before automated soldering.
• Mounting dimensions for all Connectors
should be as shown in the following diagram.
• The allowable margins for mating the Connectors are shown below.

α: 3.55 mm
The distance between the center line of the
mounting holes on the mother board and
the daughter board. (This center line is
shifted 0.3 mm toward row a from row b.)
β: 2.54 mm
The distance between the mounting holes
on the daughter board and row a.
γ: 5.3 mm
The distance between the edge of the
daughter board and row a.
δ: 12.4 to 14.2 mm
To insure reliability, be sure to keep the
Connectors within these dimensions when
mounting.
