Model 40-531-021-S is a very high density 1-pole screened 32x8 matrix module. It is also available in 2-pole or 1-pole non-screened reed relay formats: The screened version is suitable for switching coaxial signals up to 50MHz. Typical applications include signal routing in Functional ATE and data acquisition systems. These PXI matrix modules are constructed using high reliability Sputtered Ruthenium Reed Relays, offering 109 operations to give maximum switching confidence with long life and stable contact resistance. Larger matrices may be constructed bytructed by daisy chaining the common signals from multiple modules. However, for applications that require a very large matrix, Pickering s BRIC modules are best suited.
