Expandable PCB Retainers

Elma Electronic is introducing the first in its family of SureLock multi-segment, extruded aluminum retaining devices.  The new 325 Series securely holds in place printed circuit boards (PCBs) mounted directly to the board and slid into a channel in the cold plate.

A simple turn of a screw enables SureLock to expand and securely hold the card assembly in place, eliminating tooling costs in most implementations. This provides a uniform retention force across SureLock's entire length to continually protect cards subject to extreme shock and vibration typically found in rugged and harsh computing environments.

The superior, lightweight design facilitates conduction cooling by transferring heat from a circuit card to a cold plate or to an enclosure's extruded side walls, and makes the 325 Series highly useful in compact, mobile applications as well.

The first of several models and styles, the 325 Series features a 0.250" X 0.260" nominal cross-section, with a guaranteed minimum expansion to 0.325".   The new series is available in custom lengths from 2.15" to 12.99".   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, if required.

All Elma SureLocks are designed to conform to the DLA standard DSCC-DWG-89024 and are DFARS specialty metal compliant in their native state. Pricing for the new SureLock 325 Series starts at $18 in low volumes. Delivery is stock to three weeks ARO.
