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.

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. Daughter board Plug 0.8 mm max. Masking tape (Recommended tape: 3M Sumitomo #214) Automated Soldering Conditions (Jet Flow) 1. Soldering temperature: 250±5°C 2. Continuous soldering time: Within 5±1 s Mother board 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. 6 DIN Sequence Connectors XC7 0.8 mm max.
