Hello all, we have gotten a few requests for various connectors from the SP series by Weipu Connector, and the suffixes have raised a few questions. The majority of the numbering system can be found in the datasheet, linked here, however, not all versions of this datasheet have the complete suffix information.
Here is an example: SP1311/S4II-C
The /S4 calls out that this has 4 sockets, and the “II” calls out the larger of the two cable diameter options marked in the datasheet. Worth noting is that this space in the part number is filled with either an “i” or “ii” and not a “1” or “11.” People often mix these up when the font is unclear.
The last piece is either a “-C” or “-N” which calls out a sealing cap included for -C, and no cap for -N.
Hope this helps!
