Performance and Dependability for Mission Critical Applications

Whether for sustainment or modernization, nVent SCHROFF’s rugged offering is well suited for protecting critical applications such as integrated battle communications, logistics and fleet operations, and radar systems.

Product Portfolio

Toolless & Torque Limiting Card-Loks

Designed for second level and field maintenance applications where a module needs to be removed and re-installed often without specialized tools.

VITA Conduction Cooled Assemblies

Optimized clamshell and heat frame designs to get more heat out of the board.

High Thermal Sawtooth Card-Lok

Best in class thermal performance in a small profile Card-Lok

Board Tolerance Compensating Extractors

VITA compliant extractor with spring PAWL design that compensates for board tolerances, puts positive pressure on pins during Card-Lok actuation and can be operated with a gloved hand.

Rugged EuropacPRO Subracks

EMC shielded subrack rugged enough to withstand shock and vibration up to 25g.​

Product Spotlight: Extractors & High Thermal Sawtooth Card-Loks


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.

Compliant with VITA 48.4 & 48.2

High Thermal Sawtooth Card-Loks

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).

Meeting advanced requirements for heat dissipation and shock and vibration resistance

Allows for up to 15% increased thermal performance over similarly sized card locks

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

Reliably secure and cool mission-critical electronics in military and defense as well as commercial aerospace applications

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
