MIL-STD-1553 Data Bus Couplers
There are two types of couplers to choose from; The In-Line type or the flange-mounted BNC connector Box-type.
In-line couplers generally offer significantly lower weight and are usually mounted by lacing them into cable bundles or securing them to bulkheads with a clamp.
Box-type couplers, although heavier, offer the advantage of easy fault isolation, flexibility in updating when a bus configuration changes, and are easy to install and repair.

In-Line - Micro CouplersFlight qualified units are available both with and without internal terminations.
In-Line MIL-STD-1553 Quik Clik CouplersQuik-Clik couplers provide a way to reduce the number of connectors and solder joints in the network, thereby improving reliability significantly.
In-Line - Thru-Hole Mounted CouplersFor applications where lacing into a cable bundle or mounting using a clamp is not practical. These couplers are flight qualified and have successfully completed a 1000 hour life test at +125°C and 100% duty cycle.
Printed Circuit Board Mounted CouplersEnables the 1553 network designer to minimize the number of connectors by mounting the couplers on a printed circuit board within the power and signal distribution box.
Internally Terminated CouplersAll North Hills' data bus couplers are now available with dual bus terminators internally mounted. This can simplify implementation of small networks (up to 8 stubs) significantly by eliminating the expense, inconvenience and parts count of external terminators.
