KA SerieS connectorS
The KA Series connector family is part of Smiths Connectors’ portfolio of interconnect
solutions designed and developed for rugged applications in the military, aerospace
and commercial aviation markets. The KA Series is a highly engineered connector
family that has gained a reputation for reliability under all varieties of extreme
environmental conditions.
Utilizing the field-proven capabilities of the Hypertac® hyperboloid
contact technology, the KA Series provides immunity to detrimental
fretting due to shock and vibration, industry leading mating cycles and
durability in a connector that meets the performance requirements
of MIL-DTL 55302. With more than 2,500 configurations, the KA
Series provides design flexibility not available with other MIL-DTL
55302 connectors. Additionally, the KA Series supports a current
rating of 4 Amp per contact, low contact resistance and minimal
insertion and extraction forces.
The technological innovation that Smiths Connectors has designed
into the KA Series enables it to provide a significant edge in
demanding military, aerospace and commercial aviation operating
environments where performance and reliability is essential.
