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
