SR4220SMT

THIS PRODUCT IS OBSOLETE.
For new designs, use the SR4220SM.

The SR4220SMT Receptacle is a board-mount interface connector for all Datakey’s SlimLine™, Extended SlimLine, NFX, and RUGGEDrive™ Tokens (see token data sheets for more details). The SR4220SMT 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 SR4220SMT 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 factory for this option with NFX, DFX, and UFX Tokens).

The SR4220SMT Receptacle is a space-saving component that mounts directly onto a printed-circuit board. The SR4220SMT is a modified version of the standard SR4210SMT -- the mounting flange has been removed for space savings. Since the mounting flange has been removed, special care must be taken in the design of the mounting of these receptacles to ensure that no stress is placed on the leads. The SR4220SMT is also available with through hole leads (SR4220PCB).
