I am looking to have custom cables mass produced (ie, hundred+ units); my usual custom cable place, however, only accepts designs submitted with their online tool, which does not support connecting multiple wires to one pin of a connector or making a Y-type cable. They also don't support having one end of a wire not connected to anything (ideally I'd like the other end stripped and tinned). I need both of those!
Here are a few specific examples that I want (there are others along the same lines):
One cable, 4 conductors, 4p dupont connectors, maybe half a dozen connectors, a couple of inches apart. Each connector has the same connections, so that pin 1 on each connector is connected to pin 1 on all the other connectors, and so forth. Use case - connecting a common 2-wire bus plus power and ground to multiple modules with the same pinout (I don't control design or manufacture of the modules, so I can't add a second connector to the design and just use straight-through cables).
10-foot cable with JST-SM-2 connector at either end (male one end, female the other), and at one end, a 3 inch wire on each of the conductors, with no connector on the other end. Use case: 4 sections will be daisy chained, the cable carries 19.5v, and the short lengths of wire would be soldered to a DC-DC converter to power the device for that section.
Does anyone know any place that can make me cables like this at sane prices? Ideally with an automated tool to place orders - but if not that, at least some way to get an idea of their pricing (not an "email for quote" runaround - this IME has always meant the price is astronomical; if their prices weren't crazy high, they wouldn't need to hide them behind a "email for quote")
