Appendix A:
Specifications
Mechanical
The reader housing is molded from sturdy, UL-94V0 rated plastic and is approximately 4.7"
deep, 1 .0" high (without stand) and 3.3" wide. The unit can be mounted to a wedge shaped
stand for desk top use which extends the height to 3.5".
The Model 152 accepts ISO 7816-1/2 cards. The gold plated ICC contacts allow a sliding action
to ensure reliable contact. The contacts are dome shaped and partially recessed which reduces
the possibility of contact damage from vandalism or normal use.
The Model 152 can be operated on or off its stand. Rubber feet (included), which can be affixed
to either the stand or the bottom of the unit housing, provide non-skid operation. Molded indents
in the unit and stand easily accommodate velcro strips, if that method is desired, and molded
keyholes allow more secure mounting. The unit may be easily removed, by squeezing both
sides of the stand.
Force required to insert or remove an ICC:
Insertion 10N maximum Extraction 3N minimum
Durability:
In excess of 100,000 card insert/withdrawal operations
Electrical
The Model 152 has several optional safeguards to protect cards and insure proper ISO
sequencing on power down.
Overvoltage protection is provided to ensure that the voltage to the card never exceeds 5.7
volts. Another optional circuit can provide undervoltage protection to ensure that the voltage to
the card never falls below 4.3 volts.
Current limiting of approximately 250mA is a standard feature of the user card supply.
