Fremont, Calif. Using a new two-step design, Elma Electronic's new AdvancedTCA handles provide a fail-safe method for the insertion and removal of ATCA boards by separating the locking/switching mechanism from the extraction function. In some cases, with a one-step process, it causes the handles to disengage too quickly, or makes it difficult to plug the ATCA boards back into the chassis, said the company.
How the two-step process works: The latch is depressed to unlock the handle, which activates the switch. This allows time for the blue LED to initiate, showing that the board can be unplugged. Once unlocked, the handle shafts are unlatched to remove the blade. The reverse process takes place during insertion of the blade. As soon as the blade is fully inserted, the latch locks the handle positively.
The new ATCA handles are made from stamped sheet metal and a rugged, hard plastic for the unlocking mechanism. For improved ergonomics, the handle louver on the shaft has been flattened and rounded for a better grip.
Pricing for the ATCA handles start at less than $3.00. Delivery is four to six weeks.
