SR4210SM

The SR4210SM is a board-mount receptacle for all Datakey SlimLine™, Extended SlimLine and RUGGEDrive™ memory tokens (see token data sheets for more details). The SR4210SM receptacle features corrosion-resistant, gold dot contacts that perform reliably over a wear life of at least 50,000 insertion/removal cycles. The receptacle includes a detent mechanism that gives users tactile confirmation when an inserted token is physically engaged. The SR4210SM also contains a Last-On/First-Off (LOFO) contact that may be used to protect the host bus by ensuring that tokens have made secure contact with the receptacle before any signals are transmitted (please contact ATEK for this option with DFX and UFX tokens). The SR4210SM receptacle is a space-saving component that mounts directly onto a printed-circuit board. The SR4210SM is also available with through-hole leads (SR4210PCB).

The SR4210SM receptacle replaces the SR4210SMT receptacle. Both receptacles share the same PCB footprint; however, the SR4210SM receptacle contact tails are now roughly coplanar with the bottom of the receptacle body, whereas the SR4210SMT contact tails had an intentional toe-down angle.
