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. RoHS Compliant ■ Connectors Model Appearance Page XC7A XC7B XC7C XC7D Plug with right-angle terminals Socket with straight terminals Plug with right-angle terminals Socket with straight terminals 2 3 4 ■ Ratings and Characteristics 5 ■ Materials and Finish Rated current 2A Item Plugs Rated voltage 300 VAC Housings Contact resistance 20 mΩ max.
