SR4230SMT

THIS PRODUCT IS OBSOLETE.
For new designs, use the SR4230SM.

The SR4230SMT 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 SR4230SMT Receptacle features corrosion-resistant, gold dot contacts that perform reliably over a wear life of at least 50,000 insertion/removal cycles. The SR4230SMT 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 SR4230SMT Receptacle is a space-saving component that mounts directly onto a printed-circuit board. The SR4230SMT is a modified version of our standard SR4210SMT -- the mounting flange has been removed and the housing has been trimmed back for maximum space savings. As a result, the token detent mechanism has been removed, reducing the token retention force. This model is therefore not recommended for applications that require significant token retention. 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 SR4230SMT is also available with through hole leads (SR4230PCB).
