The SR4220PCB Receptacle is a board-mount interface connector for all Datakey’s SlimLine™, Extended SlimLine, NFX, and RUGGEDrive™ Tokens. The SR4220PCB 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 SR4220PCB 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 SR4220PCB Receptacle is a space-saving component that mounts directly onto a printed-circuit board. The SR4220PCB is a modified version of the standard SR4210PCB -- 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 SR4220PCB is also available with surface mount leads (SR4220SMT).
