SR4220PCB

The SR4220PCB board-mount receptacle mates with all Datakey SlimLine™, Extended SlimLine, and RUGGEDrive™ memory tokens (see token datasheets for more details). The SR4220PCB receptacle features a right-angle, board-edge design with through-hole contacts.

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, SR4220PCB 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). The SR4220PCB is also available with surface mount leads (SR4220SM).
