XC7B Double-row Sockets
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/palladium plating has an insertion durability of 5,000 cycles.
- See the "Standards certification / conformity list" for information on conformity to certification standards.

(With straight DIP terminals)
• Use masking tape to mask the Right-angle Connectors before automated soldering.

- Continuous soldering time: Within 5 s
Dimensions after Mounting
• Mounting dimensions for all Connectors should be as shown in the following diagram.
α: 3.55 mm
The distance between the center line of themounting holes on the mother board andthe daughter board. (This center line isshifted 0.3 mm toward row a from row b.)
β: 2.54 mm
The distance between the mounting holeson 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.
• The allowable margins for mating the Connectors are shown below.
