Contacts are normally included with the D38999 D38999 series of connectors, however a number of exceptions do exist.  One of them is when the part number used to order the connector has an “-LC” suffix at the end.   Another exception is how the part number is assembled.  Normally at the end of the part number there’s a “P” or ‘S” to denote the gender of the contacts used in the connector (“P” for pins, “S” for sockets).  If these are switch to an “A” or “B”, then the contacts are again omitted and must be purchased separately.   Some example part numbers are shown below.

These 2 part numbers include contacts.
