7, 9, 11 (depending on decoder type) single wires with free ends (120 mm long).

8-poliger Stecker


MX621
R, MX630R, ...

8 pin plug to NEM652 standard (i.e. "medium interface" as specified in NMRA 9.1.1) on 70 mm long wires.

6-poliger Stecker

MX621
F, MX630F, ...

6-pin plug to NEM651 standard (i.e. "small interface" as specified in NMRA 9.1.1) on 70 mm long wires..

6-poliger Direktstecker

N , MX646N, ..

6-pin direct plug to NEM651 standard (i.e.  "small interface" as specified in  NMRA) on decoder.

21-polig Schnittstelle


MX631
D, MX644D,

The 21-pin interface,
"MTC",
direct on decoder follows
NMRA DCC RP 9.1.1, based on 22-pin plug and socket connections (one anti rotation pin as index),.

PluX16 Connector

MX630P, MX645P

"PluX" (pictured is the 16-pin example in the upcoming standard for vehicle to decoder connector in the DCC world, also in the NMRA DCC RP 9.1.1.



MX618N18, MX658N18  
       
21-Poliger Stecker


Uses the 21-pin interface e.g. found in vehicles by Marklin, Trix, Brawa, Roco, and also in some 0-track vehicles.


8/16/22-poliger Stecker


Compared to the existing 21-pin interface pins can be better utilized, because none are "wasted" for C-Sine motors (Hall1, Hall2, ..) .

"PluX" type connectors will be available in four versions: 8-pin, 12-pin, 16-pin and 22-pin.

The standard for PluX interfaces is designed so that decoders with a smaller size plug (with fewer pins) can be used  in a larger socket. In the diagram various colours have been used to show the smaller designs: 8-pin is yellow, 12-pin red and 16-pin brown. In all cases the index pin is 11, but the numbering does not start from 1 (except in the 22-pin version).
