KEL's unique Seesaw Contact Method distances the mechanical section that makes physical contact with smart cards from the electrical connection points and deploys the contact section within a recess in the insulator, thus preventing the buildup of dust and the resultant contact instability.
In this regard, the ISC3-5 Series provides connectors with stronger guide sections than those of the ISC3 Series.
The connectors of this series are, therefore, the ideal choice when a higher level of stability is required at the card insertion slot.
