SR4220VRT

The SR4220VRT board-mount receptacle mates with all Datakey SlimLine™, Extended SlimLine, and RUGGEDrive™ memory tokens (see token datasheets for more details). The SR4220VRT is a vertical,
board-mount receptacle. For right-angled board-edge designs, see the SR4220PCB and SR4220SM receptacles.

All Datakey SlimLine receptacles feature “gold dome” contacts that perform reliably over a wear life of at least 50,000 insertion/removal cycles and employ a wiping mechanism to remove debris or build-up
on the token’s contacts each time a token is inserted or removed. Also, SR4220VRT receptacles include a detent mechanism that contributes to token retention and gives users tactile and audible confirmation when an inserted token is fully engaged. The token/receptacle system provides a Last-On/First-Off (LOFO) contact that is used by system designers to detect when a memory token has been inserted or
removed (contact ATEK Access Technologies for token detection details for RUGGEDrive memory tokens)
