The 40-533B-022 is a 64x4 2-pole ultra high density matrix module . Other configurations are 64x4 1-pole and 64x2 1 or 2-pole reed relay formats. 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 by daisy chaining the common signals from multiplemodules. However, for applications that require a very large matrix, Pickering s BRIC modules are best suited.
