NGFF edge connectors

I want to buy an ngff edge connector. The producer of my device states that they are using industrial standard M.2 Type2242 E-Key (NGFF) pin interface. I cannot locate the types and keys of the ngff edge connectors in digikey website.

There is no info about the types of the ngff edge connectors. ın addition, I cannot understand which product is for which type and key?

Thank you
