SL100: Where to get matching connectors

All sales versions of the board come with matching connector housings and contacts. In a volume OEM situation you would most likely have a wiring harness pre-made by a specialist contractor, ready to just plug onto the board and attached devices.

The large, white, single pin-row connectors on the board are commonly referred to as "KK". They are 0.156" or 3.96mm pitch. Matching female connectors are available from a number of manufacturers. They are available in two principle styles:

If you use the IDC types you will also need a suitable crimping tool. Please ask your connector supplier for a suitable type. We recommend a good quality ratchet tool and proper operator training. The most common cause of connection failure is improper crimping.

Note, too, that the contacts are designed to handle a defined range of wire gauges. Take care to use the correct gauge of wire, or you will have problems.

The following table lists a number of connector manufacturers. In the housing part number ??? represents the number of poles (contact positions). Fill unused ? positions with 0's, i.e. for 4-way "???" becomes "004"
