Circuit board lock retainers for military and aerospace embedded computing introduced by Elma
FREMONT, Calif., 9 Dec. 2014. Elma Electronic Inc. in Fremont, Calif., is introducing the 325 series of SureLock multi-segment, extruded aluminum retaining devices that hold in place printed circuit boards mounted to the board and slide into a channel in the cold plate.
The circuit board retainers are for embedded computing in military and commercial in-flight electronics; mobile communications systems and networks; railway-control systems; electronic monitoring, control and guidance equipment; conduction-cooled small-form-factor systems; and public safety networks.
A turn of a screw enables SureLock to expand and hold the card assembly in place to provide a uniform retention force across SureLock's length to protect cards from extreme shock and vibration typically found in rugged and harsh-environment computing environments.
The lightweight design facilitates conduction cooling by transferring heat from a circuit card to a cold plate or to an enclosure's extruded side walls in compact, mobile applications.
The 325 series features a 0.25-by-0.26-inch nominal cross-section, with a minimum expansion to 0.325 inches. The series is available in custom lengths from 2.15 to 12.99 inches. Other options include hex-drive style, mounting holes and types, length and finishes as well as a visual indicator, a locking element, or a captive feature.
Elma SureLocks are designed to conform to the DLA standard DSCC-DWG-89024 and are DFARS specialty metal compliant in their native state.
