Electrical RF multi cable design
Budget: $30 – $250 USD
Vendor is responsible for materiel acquisition and expedited shipping costs will be approved contingent upon notification to offeror.
Qty 6 mated assemblies consisting of 1) a terminated cable, and 2) bulkhead with terminations. The cable will connect the bulkhead assembly to a device. The bulkhead will pass through the wall of an enclosure and connect the device to several sources within the enclosure. I will refer to the cable ends as SOURCE and LOAD, with the SOURCE end connecting to the bulkhead, and the LOAD end connecting to the aforementioned device. The largest gauge wire possible is preferred for performance.
1) 24” Fully shielded 7mm OD 16-conductor cable (diameter is negotiable but must be specified to support post-build ferrite addition).
a) the LOAD end of the cable shall use a connector mechanically and electrically compatible with FGG.1B.316.CLAD62 (Lemo B series). This cable end interfaces with an existing device. It is understood that this connector series does not surpass IP5X rating, but IP67 or greater is preferred.
b) the SOURCE end of the cable must use a connector that is IP67 rated or greater. The key requirements are environmental and stock availability to meet the timeline. The following part meets the requirement but we are open to alternatives: S21K0C-P16MCC0-500S
c) One pair of conductors will be transmitting baseband video. Coaxial cable is preferred for this transmission.
d) the cable will exist outdoors, so the external covering should be UV resistant and waterproof. No chemical resistance is required.
e) The "device" generates significant common mode EMI up to 600MHz, so shielding must be continuous along the cable.
2) Bulkhead connector assembly supporting materiel thickness inclusive of .04" - .08". The bulkhead connector must be rated for IP67 or greater. The mating connector to the LOAD cable end listed above is G11K0C-P16LCC0-0000. We are open to alternatives.
a) The power lines should be 12" flying lead wires with each group-of-three + and - lines twisted and soldered together ending in a single + and a single - 11mm tinned end.
b) The shield pin wire should be 12" long
c) The video lines should be a 24" flexible coaxial cable terminating in a male BNC connector
d) The USB line should be a 24" flexible cable and terminate in a USB type A connector. A smaller backshell is preferred.
e) The RS-232 lines should be 24" wires with 12mm tinned ends.
