Go to Samtecs website, they should have a link for their
distributors and oem contacts.
Thanks. The site Findchips led me to Arrow who ships them in for the Netherlands.
I ordered 10 connectors part # FTSH10501LDVK from Arrow electronics. The were $2.54 each and were drop shipped to me directly from Samtec. If you are a big fish company you might try calling Samtec for a few samples.
