Uniform retention force ensures secure assembly in PCB retainers
An expanded line of card retainers from Elma Electronic provides uniform retention force across the entire length of the device to ensure PCBs are held securely in place. Now available in more length and profile options, the SureLock family of multi-segment, extruded aluminum retaining devices is suited for rugged applications where PCBs slide into a channel in the cold plate assembly or enclosure.
A simple turn of a screw expands the SureLock retainer to securely hold the card assembly in place, eliminating tooling costs in most implementations. An added benefit is a uniform retention force across SureLock's entire length to continually protect cards subject to extreme shock and vibration, as typically found in rugged, harsh or otherwise challenging computing environments.
Walter Podbelski, Director of Business Development, Elma, said "For embedded electronics in mobile applications that require conduction cooling, SureLock not only holds cards securely in place, but facilitates heat transfer as well. Widely used in ruggedised military and defense applications, this growing family of PCB retainers is finding a home in other areas, including small form factor industrial systems."
The lightweight, aluminum construction not only makes the SureLock Series highly useful in compact, mobile applications, but also facilitates conduction cooling by transferring heat from a circuit card to a cold plate or to an enclosure's extruded side walls.
Available in three standard lengths, the expanded series is available in custom lengths from 2.15 to 12.99". Standard nominal cross section profile sizes are 5.7x 5.7mm for the 290 Series; 6.4x6.6mm for the 325 Series; and 9.3x9.5mm for the larger 460 series.
