nVent announced the release of the Positive Retraction Card-Lok, used in rugged environments when a printed circuit board (PCB) must be reliably removed from a chassis in the field.
Â
The positive retraction mechanism allows the Card-Lok to disengage from the wall of the chassis by eliminating the stiction. The Card-Lok is then able to retract, and the PCB can be removed from the Chassis, allowing access to vital electronics.
Â
These standard COTS or modifiable versions are drop-in replacements of the nVent SCHROFF 260, 265, and 280 Calmark & Birtcher lines. In addition, these Positive Retraction Card-Loks provide better clamp force and thermal management than their standard Card-Lok series equivalents.Â
Â
Designed and manufactured in an AS9100 certified factory in San Diego, California, the Positive Retraction Card-Lok meets VITA (46, 48.2, 48.4, 48.5 and 48.8) and SOSA standards along with being DFARS, JOSCAR, and ITAR compliant. Also meeting advance requirements for shock and vibration resistance.
Â
The nVent SCHROFF’s Positive Retraction Card-Lok recently won the prestigious Best in Show Award by Embedded Computing Design at Electronica 2024 Exhibition and Conference.Â
