databus couplers

Ultra-lightweight, with a low profile

Compact, in-line, splice-terminated data bus microcouplers feature a lightweight design that meets the MIL-STD-1553B requirements for hardware configuration and performance. The low-profile configuration enables avionics systems designers to plan for optimum couplet locations. Microcouplers are also available in space-grade materials. TE's Raychem technology builds on 20 years of experience and continuous improvement in data bus to offer ultra-lightweight, in-line microcouplers in 1 to 6 stub configurations.

Ultra Lightweight In-Line Microcouplers

1 Through 6 Stub

A new family of ultra light-weight In-line micro-couplers, available in 1 through 6 stub configuratioins. These couplers offer the same high performance and reliability as current microcouplers, but their weight is further reduced. These are available in configurations up to 6-stub and to minmize weight: there is no option for a mounting eyelet. Combined with TE 24 AWG or 26 AWG data bus cables, these ultra light couples allow designers to significantly reduct weight.
