The Keithley 7035 is a 9-bank, 1 x 4 multiplexer card that routes signals across nine independent banks, each with 2-pole Form A (Hi, Lo) switching. Designed for automated testing, data acquisition, and process monitoring, this card delivers flexible signal management with banks that can be externally combined for complex switching configurations. Contact resistance below 1Ω per conductor and contact potential below 1µV per channel contact pair ensure signal integrity in precision measurement systems.
