KFT Series provides a low profile, dual row in-line interconnect solution ideally suited for stacking and use in areas where board real estate is at a premium. With the increasing need to reduce size and weight, KFT is designed to be miniature, allowing higher signal counts in smaller spaces by providing a 0.050 in. (1.27mm) contact pitch and a board-to-board stack height of just 0.343 in. (8.71mm).

Like all Smiths Connectors products, KFT connectors are highly engineered to allow for top performance under all dynamic environmental conditions. Through the use of the proven 0.40mm Hypertac® hyperboloid contact, KFT connectors provide immunity to shock and vibration fretting, numerous linear paths of contact, and a self-cleaning wipe action that results in consistently better signal integrity for high reliability applications across a wide range of industries. The Hypertac contact system offers low insertion and extraction forces, low contact resistance, as well as industry leading mating cycles in the tens of thousands.

Manufactured with 30 percent glass filled liquid crystal polymer (LCP) insulators and potted contacts, KFT connectors withstand the high temperatures associated with soldering. The LCP insulators also exceed NASA space requirements for outgassing and have inherent keying features to prevent improper mating.

KFT connectors are also available with optional snap-on mounting brackets for additional support. KFT Series connectors perform under the most severe conditions, giving them the edge in demanding critical applications for military, aerospace, industrial, and medical devices where failure is not an option.
