Calmark Torque-Limiting Card-Lok Retainers Prevent Board Damage
Warwick, RI, May 2009--New Calmark(TM) Series 223 and 224 five-piece Card-Lok retainers for cold plate-heat exchanger applications feature a patent pending torque-limiting design that prevents damage to the card-lok or to the board module assembly caused by over tightening.
A standard hex wrench can be used to lock the board module assembly into the cold wall, providing a safe clamping force without the need for a torque wrench. A screw actuated wedge action locks the board module assembly into place for high reliability and maximum shock and vibration resistance. An alignment spring returns wedge bodies to the relaxed position when unclamped.
The wedge action design also provides maximum contact between thermal paths on the board module assembly and the heat-sinking surface for maximum thermal transfer. Calmark Series 223 and 224 Torque-Limiting Card-Lok retainers are available in a wide range of standard lengths, mounting configuration options and finishes. There are also many custom options available, including three-piece assemblies, non-standard mounting patterns and non-standard finishes.
