  • The 260HC features a unique wedge design provides more than triple the clamping force of similarly sized Card Loks, providing superior protection in high shock and vibration applications. The 260HC can be a drop in replacement for most existing Series 260 Card Lok applications.


    Like all shafted Card Loks, the Series 260HC has a ridged shafted design for a more uniform clamping force over the length of the card lok, while maintaining wedge and body alignment for easier installation.


    The Card Lok mounts to the PCB either by screws or rivets, with one Card Lok on the top of the PCB and one on the bottom. Often Card Loks are installed within a conduction cooled card cage where the PCB, with the two Card Loks attached, is then installed into the cold wall channels. When actuated, the Card or Wedge Lok clamps the PCB firmly to the cold wall to facilitate board retention and thermal transfer.


    From time to time, Pentair Equipment Protection may modify its product specifications to be in conformity with applicable industry, military or other relevant standards. Unless otherwise mutually agreed in writing, cancelled or superseded military specifications may be certified to the latest or superseding specifications. Products manufactured in conformity with such specifications will be deemed fully compliant whether or not you have been notified of such modifications, even if different from the original specification or those referenced by the customer.
