KVPX Shielded High Density PCB Connector


  • Fully footprint compatible with VITA 46 and VITA 48 standards
  • Utilizes industry guide hardware
  • Verified for 6.25Gbps data rate performance
  • 100 ohm impedance for differential pair configurations
  • Flexible modular design for standard 3U and 6U as well as custom configurations

Smiths Connectors KVPX connector is a shielded, high-density, high-speed, modular interconnect system optimized for differential pair architectures on a 1.8mm x 1.35mm grid. The waferized daughter-card assembly also provides single-ended and power wafer options. The backplane modules are available in 8 and 16 row increments on a 1.8mm x 1.8mm grid, with user-configurable keying and integrated stainless steel guide pin/keys. The KVPX connector platform offers the ability to scale from 80 Mbps to over 10 Gbps while retaining the same Vita 46 backplane slot pitch at 20.3mm to 25.4mm.

Through the use of the proven 0.40mm Hypertac® hyperboloid contact, KVPX 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. Manufactured with 30 percent glass filled liquid crystal polymer (LCP) insulators and potted contacts, KVPX 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.

KVPX Series connectors perform under the most severe conditions, giving them the edge in demanding critical applications for military, aerospace, industrial, and medical devices.
