    The 263HC 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 263HC can be a drop in replacement for most existing Series 263 Card Lok applications.

    Applications:

    The Series 263HC Card Lok also features a lighter weight, narrow profile ideal for retaining PCBs that are densely populated within the enclosure. The shafted design provides more uniform clamping force over the length of the card lok, while maintaining wedge and body alignment for easier installation.
