I need to select a connector type for 16 pair of wire. The signal is analogic and in the frequency range of 1 MHz. I prefer not to use 16 SMA connectors, however I am fine to use 4 blocks of connector or less. The connectors would be preferably shielded.

Get a shielded Ethernet cable:

This gives 4 shielded pairs, so just ground the white wire. You need 16 connections, so get 4 Ethernet cables. Voilla.


EDIT

This appears to be more of what you need. enter image description here


If I were you I would seriously just get some aluminum foil and wrap it around small cables and then put a heat shrink tube around the whole thing. (And ground the aluminum foils)
