The Keithley Series 7000 switch card family is a selector-guide catalog of plug-in cards designed for use with the Keithley 7001 and 7002 switch mainframes. The guide organizes the cards into functional groups — High Density, Control, High Current, High Voltage, Low Current, and Low Voltage — and lists for each card the channel count, configuration (multiplexer, matrix, isolated switch, or digital I/O), contact configuration, maximum voltage, maximum current, maximum power, contact potential, maximum offset current, recommended frequency, connection type, and CE marking status.

Within the catalog, customers select cards according to the signal-routing task at hand. Multiplexer cards such as the 7011 and 7111 series provide four independent 1×10 multiplexers with connection to the mainframe backplane. The 7012 matrix card provides a 4×10 matrix with rows connecting to the analog backplane. Isolated switch cards including the 7013 and 7036 provide independent channels of one- or two-pole switching.

ValueTronics maintains a deep inventory of Keithley switching products and accessories at our 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where each instrument is received, inspected, and tracked through our own facility rather than drop-shipped from an unseen third party. Sourcing a specific 7000-series switch card — whether a low-current 7152 matrix, a high-voltage 7154 multiplexer, or one of the high-density multiplexer or isolated switch cards — often requires matching the right cable, connector kit, or screw-terminal assembly from the accessories table, and our in-house staff handles that matching directly so the configuration you receive is the configuration you need.

Brand Heritage

Keithley Instruments was founded in 1946 in Cleveland, Ohio, and built its reputation in precision low-level electrical measurement and switching. The company was acquired by Danaher Corporation in 2010 and, alongside Tektronix, became part of Fortive Corporation when Danaher spun off its industrial businesses in 2016. The Keithley brand and product lines, including the 7001 and 7002 switching mainframes and their plug-in cards, continue under the Fortive group with shared service and distribution infrastructure with Tektronix.

Compare Other Models in This Series

The Series 7000 switch card family is presented in the selector guide as a structured catalog: cards are grouped by application class (High Density, Control, High Current, High Voltage, Low Current, Low Voltage), and each row lists the channel count, card configuration, contact configuration, electrical ratings, contact potential, offset current, recommended frequency, connection type, and CE status. This layout lets a user match a switching task to a specific card by working across the row of specifications.

Connector-suffix conventions in the family separate cable-connector versions from screw-terminal versions of the same card. For example, the 7011 is offered as 7011-C (connector, MTC-cable connection) and 7011-S (screw terminal), with the screw-terminal version specified at a tighter contact potential of <500 nV versus <1 μV for the connector version, as listed in the selector guide.

Each card model below is its own dedicated product page with condition-matched pricing. Each pre-owned listing in the Series 7000 switch card family is evaluated against the specifications in the selector guide for its specific model — voltage and current ratings, contact potential, offset current, recommended frequency, and connection type — so the card you order matches the row in the selector guide for that part number.

The most important distinctions across the family are the application class and the connection type. High-density multiplexer and matrix cards (7011, 7012, 7015, 7018, 7035, 7111) operate at up to 110 V or 175 V with 1 A current ratings and recommended frequencies from 500 kHz to 10 MHz, depending on model. Isolated switch cards (7013, 7036) and digital/control cards (7020, 7020-D, 7037-D) extend the family into per-channel switching and digital I/O.

Specialty classes broaden the envelope: the 7053 reaches 300 V at 5 A for high-current switching; the 7154 reaches 1100 V at 500 mA for high-voltage routing; the 7152 and 7153 low-current matrix cards reach 200 V and 1300 V respectively with sub-picoamp offset currents; the 7158 routes low-current signals through BNC connections; and the 7168 supports low-voltage switching at sub-30 nV contact potential. Refer to the comparison table that follows for the per-model specifications drawn directly from the selector guide.

Important: This is a selector guide for switch cards used in the Keithley 7001 and 7002 mainframes; the accessories table also covers cards used in the 705 and 706 mainframes. Confirm mainframe compatibility and required cables, connectors, or terminal kits from the accessories table before ordering.Important: The 7065 Hall Effect Measurement Buffer Card is referenced in this selector guide; see page 211 of the source catalog for detailed specifications.Important: Cards designated -C use a connector interface and require a mass-termination cable (e.g., 7011-MTC-1 or 7011-MTC-2); cards designated -S use a screw terminal block (e.g., 7011-ST, 7012-ST). The required cable, connector, or terminal accessory is not included with the card and must be ordered separately.Recommended pairing: when ordering a screw-terminal high-density card (7011-S, 7012-S, 7013-S, 7015-S, or 7018-S), include the corresponding screw-terminal assembly (7011-ST, 7012-ST, 7013-ST, 7015-ST, or 7018-ST) from the accessories table.
