This is 7 x 0.2mm multicore cable, and is the correct size for wiring our controller IDC connectors to switches and potentiometers.
Available as 3 core, 4 core, 6 core or 8 core cable. Each core is a separate insulated conductor, and each conductor consists of seven strands of 0.2mm² tinned copper wire (hence 7 x 02 cable). It is un-screened.
We strongly recommend using this size cable with our IDC connectors. Thicker cable can cause short circuits in the connector, while thinner cable can cause intermittent connections. Please please please don’t use single strand bell wire – it’s horrible stuff for this application
