Board mount smartcard connectors with ribbon cable
10 March 2004
Interconnection
Board-mount smartcard connectors with IDC termination from Tyco Electronics enable designers to remotely locate the smartcard slot from the main board, while ensuring easy maintenance. The smartcard connector features a ribbon cable with strain relief, various cable lengths and versions offering 8 and 16 contacts.
Operating over -10 to +70°C, the connector is current rated for class-A 100 mA signals and class-B 50 mA, withstanding transients of 1 A. Voltage rating is ISO/IEC 7816-3 class-A 5,5 V and class-B 3,3V maximum. Withdrawal force is 2N minimum and insertion force is 10N maximum. Excluding cable and IDC connector, termination resistance is 100 milliohm, maximum for data contacts and 150 milliohm for the switch contacts. Dielectric withstanding voltage for both data and switch contacts is 200 V d.c. or 250 V rms at 50 Hz.
In a high temperature thermoplastic housing, the smartcard connector has phosphor-bronze contacts, plated gold over nickel on the mating areas and tin-lead over nickel on soldering areas. The connectors are rated at 30 000 cycles durability and designed to withstand 20 minutes random vibration over 10 to 500 Hz in each of three perpendicular planes.
