There are three different "capacity" connectors in the Deutsch "DT" family.
DTM - available in 2, 3, 4, 6, 8 and 12 way are rated up to 7.5amps for 24, 22 and 20awg wire
DT - also available in 2, 3, 4, 6, 8 and 12 way are rated up to 15amps for 20, 18, 16 and 14awg wire
DTP are available in 2 and 4 way and are rated up to 25amps for use with 14 and 12 awg wire
There is also a single way connector in the HD family which uses the same terminals as the DTP connector.
The nice thing about the DT connectors is they terminals are not much bigger than the wire so you can easily de-pin a connector (no special tools required) for servicing. Also the seals are part of the connector (vs part of the terminal on other connectors) which makes crimping and assembly easier.
