Card Seated Switch
A Card-Seated switch is operated when a card is fully inserted into the Reader (card is at the
fully rearward position). The Card-Seated switch is an integral feature of the Smartcard
Connector Block and detects when the card has properly “landed” (seated) on the smartcard
contacts. The card-seated signal at the interface I/O connector is normally open and is grounded
when the card is fully inserted into the Reader.
On insertion of the card, there may be some spurious transitions (mechanical switch bounce) at
the Card Seated output, which do not exceed 4 ms. These transitions occur before the ICC chip
contacts stabilize (stable contact with ICC pads) within a maximum of 40 ms from the stable
state of the Card Seated output.
The first transition from the Card Seated output on withdrawal of the card is guaranteed to occur
1 ms before the ICC contacts lift. During the period between the two events, the contact
resistance can increase to (but not exceed) 100 ohms for C1, C5, and C8 contacts, and 500 ohms
for C2, C3, C4, and C8 contacts. For C7 the limit is 700 ohms.
Subsequent to the first transition from the Card Seated sensor, there can be additional transitions
because of the mechanical bounce of the Card Seated switch contacts.
MECHANICAL MOUNTING
Mounting options for the Reader are as follows:
• Side Mounting Pins
• Side Mounting Slots
Side Mounting Pins
There are four molded pins; two are located on each side of the chassis. The holes are for M3 or
#4 self-tapping screws. Dimensions for mounting with pins are shown in Appendix A.
Side Mounting Slots
Four molded slots are available when pins are not provided. Dimensions for mounting with slots
are shown in Appendix A.
PCB MOUNTING POSTS
The PCB Mounting Posts are located on the upper side of the Reader. Mounting Posts may be
used for chassis or PCB mounting. The Posts are designed to accept M3 or #4 self- tapping
screws torqued to 4.0 in-lbs.
SMART CARD CONNECTOR
The IntelliStripe 70 contains a 10-pin smartcard connector with switch, which connects to the
user’s PCB assembly through a flex cable. The location of the flex cable is shown in previous
illustrations and identified in Figure 2-1.
