Pentair Introduces New High Thermal Performance Retainer Series and Newly Expanded High Clamp Force Family of Card Loks

Pentair has released a new Schroff retainer design-the Calmark High Thermal “HT” Card Lok and the newly expanded family of Calmark Series 263HC, 265HC, and 276HC High Clamp Force Card Lok Retainers.

The 280HT Card Lok provides best-in-class thermal performance by up to 15 percent over similarly sized Card Loks.  The 280HT can do this by shortening the thermal path distance from the PCB to the cold wall through a unique design.

Unlike the traditional Card Lok, the 280HT Card Lok features solid brackets along the length of the Card Lok that provide a continuous and uniform surface along the printed circuit board, or heat frame, and the cold wall.  The internal geometry maximizes surface contact area while minimizing heat path distance from the board to the cold wall.  You can view data sheet, performance data, and CAD files here.

The newly designed 263HC, 265HC, and 276HC High Clamp Force Card Lok Retainers provide an average of three times the clamping force of similarly sized Card Loks, meeting the growing demands of shock and vibration environments.  Its small and lightweight design provides industry-leading board retention that is ideal for defense, space and aerospace applications.

What is a PCB Card Guide?

Printed circuit board (PCB) card guides, also called PCB retainers, are short narrow strips of material formed into shallow tapered troughs. PC boards are inserted into the top of the trough while the bottom is secured to an enclosure wall. Most card guides secure the PCB in place through the use of pressure but some card guides utilize levers or screws to lock the PCB in place. Card guides are fabricated from a variety of materials including nylon, aluminum, beryllium copper, and stainless steel. By securing circuit boards in place, card guides prevent damage to PCBs caused by vibration and movement.

The Top Names in Card Guides

For many years Pentair, under their Schroff, Birtcher, and Calmark brands, has been the leading manufacturer of PCB card guides. In fact, many of their branded products such as Wedge Tainers, Lok Tainers, PCB Tainers, and Card Loks have become synonymous with PCB card guides.  Other top card guide manufacturers include Bivar, Essentra (formerly Richco), and Keystone Electronics.
