Model 40-536-021 is a very high density dual 1-pole 44x4 matrix module. It is also available in single 1-pole 92x4 or single 1-pole 44x8 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 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.
