Drotek NEO-M8N GPS connector?

I would like to know the exact name of the connector on the Ublox NEO-M8N GPS ( Ref. : GPS0740A05 )

It looks like a 4P JST connector 1.25mm, but there are so many, I would like to know the exact name for the connector. Maybe a datasheet?

The connector on this GPS is JST-SH 4pin.
