It would be nice to know what range of cable sizes each clamp supports. Cables are available in many sizes between 4mm, 5mm, 6mm, 7mm, etc. I have a 4.5mm cable. Do I assume that the 4mm size can clamp "down-to" 4mm, and thus accepts anything from 5mm down to 4mm? Or do I assume that 4mm is a hard limit, and it cannot support a larger diameter cable?
Agreed. I didn't think to check the other cable clamps in the datasheet. This sounds like a safe assumption since the construction of the RM12-WBP-CP version appears to be of the same style of construction.
I will add that for the RM12-WBP-CPs clamps they quote both the A-diameter of the grommet ID and a cable diameter, and they quote a single A-diameter for two different cable diameters, twice (see image below).
This led me to assume that each clamp was designed to clamp "down-to" the cable diameter listed, but would allow a cable with a diameter as high as the A-diameter. But that assumption would allow elimination of the 5mm and 7mm versions, so it's not a good assumption!!!
So, now I think I will just look for cables that meet the recommended cable diameters of 4mm, 5mm, 6mm, or 7mm, +/-.2mm.
