North Hills provides In-line data bus couplers with up to fve transformer-coupled stub output ports (units with more than fve stubs are available on special order). These units are available with and without internal terminations and are for use in applications where mounting can be accomplished by wiring the coupler into the harness. These units can be supplied with a variety of different connectors and cables (MIL-C-17/176-00002 is standard) or without connectors for splicing or integrating into
harnesses. The standard stocked units are manufactured with 12 inch long (30cm or 300mm) MIL-C-17/176-00002 cable. Couplers can also be ordered with custom cable lengths and a variety of connectors for direct installation on any system. Using in-line couplers in your data network reduces the number of connectors which signifcantly improves the calculated reliability (MTBF).
All resistors are 1 Watt per MIL-R-39007, Failure Grade S and mounted away from the transformer to minimize heating effects. The transformers are manufactured to MIL-T-21038. These couplers are Flight Qualifed and have successfully completed a 1000 hour life test at +125°C and 100% duty cycle. Copies of test reports are available upon request. Space Qualifed couplers are also available. Please refer to the appropriate data sheet for more information.
All products are 100 % tested and certifed. For maximum system reliability multiple couplers can be daisy chained at the factory into an integrated harness with no splices. Specifcation Control Drawings are available to help you document the part selected for your application.
