Keithley 7012-C 4 x 10 Matrix Card

The Keithley 7012-C is a 4×10 matrix card for analog signal switching within Keithley 7001 and 7002 mainframes. It provides 2-pole Form A (Hi, Lo) contact configuration across 40 crosspoints, with a 96-pin male DIN connector for external circuit connections. Individual rows connect to the mainframe’s analog backplane, enabling larger matrix configurations and seamless integration with complementary switching cards.
