Compact, in-line, splice-terminated data bus microcouplers, feature lightweight design
that meet the MIL-STD-1553B requirements for hardware configuration and perform-
ance.The low-profile configuration enables avionics system designers to plan for opti-
mum coupler locations.
Tyco Electronics data bus microcouplers are qualified to Raychem Specification D-6020,
European Specification EN-3567, and are specified in the Air Force drawings listed in
8340707. Standard products are supplied with Raychem SPEC 55 data bus cables,
including EMP-hardened versions.
All of these products are available assembled with other components into a complete
data bus harness without splices.
The Raychem data bus microcoupler features:
Environmental sealing

Ultra Lightweight In-Line
Microcouplers 1- through 6- Stub
Building on over 20 years of experience and continuous improvement in data
bus, including pioneering in-line microcouplers, Tyco Electronics introduces a
new family of ultra light- weight in-line Raychem Microcouplers, available in
1- through 6-stub configurations.
These couplers offer the same high performance and reliability as Raychem
current microcouplers, but their weight is further reduced. They are available
in configurations up to 6-stub. There is no option with a mounting eyelet.
Combined with Raychem 24 AWG data bus cables, these ultra light couplers
allow designers to significantly reduce weight. An unfilled flat braid cable is
available for additional weight savings.
They are also available assembled with other customer specified components
into a complete factory-built and tested data bus harness.

Triaxial Connectors and Terminators
to European NORME EN3716 for
1553B Data Bus Cable
Now, both high-density packaging and full shield
coverage are available with a simple, quick and reli-
able termination system. AWG24 twisted-pair data
bus cables are terminated to triaxial SolderTacts con-
tacts, which fit size 8 cavities of MIL-DTL-38999,
Series I, III, or IV connectors.
Raychem brand triaxial 38999-type data bus contacts
deliver the signals with:
One-step termination
Termination time of 1 to 2 minutes
No needed special termination tools
No requirements for special skills
Reworkable and repairable terminations
Strain relief that is built into the design
Continuous 360° shield coverage
Triaxial mating face for least susceptibility to
Rugged construction
Inspectable solder terminations
Low voltage drop and high reliability due to
precisely controlled solder termination.
Raychem size 8 triaxial data bus contacts for MIL-DTL-38999 connectors have interfaces
that comply with MIL-C-39029/90 and /91 to provide intermatability with crimp contacts.
These contacts provide a fast and convenient method of implementing MIL-STD-1553B
connections in MIL-STD-1760 applications.
