DIN Socket Sequence Connectors XC7 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.
