High Thermal Sawtooth Card Lok

High Thermal Sawtooth Series

nVent SCHROFF's NEW High Thermal Sawtooth (HTS) Card Lok is evolving the traditional card lok to better satisfy industry requirements for defense and aerospace in conduction cooled systems. With a cost-efficient design, the HTS series meets advanced performance demands for Size, Weight and Power (SWaP).
Features and Benefits

  • Reliably secure and cool mission critical electronics in military and defense as well as commercial aerospace applications
  • Meeting advanced requirements for heat dissipation and shock and vibration resistance
  • Allows for up to 15% increased thermal performance over similarly sized card locks
  • The HTS series minimizes thermal resistance and allows for heat to flow almost directly from the board to the cold wall
  • Featured sawtooth design provides a continuous and uniform surface along the PCB/heat frame and along the cold wall
  • Allows for up to 91% higher clamping force over similarly sized card locks (280HTS)
  • Drop-in replacement for series 260, 265, and 280 nVent SCHROFF card loks

Conduction Cooled Assemblies (CCA's)

Designed to retain and cool PCBs in rugged, heavy shock and high vibration environments commonly found in military and defense and commercial aerospace systems.

Features and Benefits
  • Order one part for the assembly: kitting including CCA, Card Loks, extractors, thermal pads, gasket and mounting hardware to simplify order management
  • High thermal CCA designs, with option of integrated HTS series card lok
  • Downloadable CAD/STEP files based on VITA standards
  • Custom design and build to print
  • 3D printed prototypes for fit checks at no cost

EXTRACTORS

The need to simplify and streamline maintenance has resulted in Two-Level Maintenance requirements. Conduction cooled assemblies equipped with HTS Card Loks can be paired with 311 Tolerance Compensating Extractors to ensure effective and efficient maintenance.

Features and Benefits
  • Self-compensation for board tolerances
  • Positive pressure on connectors during Card Lok actuation
  • Compliant with VITA 48.4 & 48.2
  • Provides 10:1 mechanical advantage
  • Other high load extractors according to VITA and IEEE standards available
