Cost Effective Switching Solution
Our low-density PXI switch matrix modules are a cost-effective solution for applications that require relatively small matrices in the PXI format. These low-density switch matrices can be expanded by connecting together multiple modules, however, we recommend that users look at the higher density switch matrix modules that involve less user configuration.
Reed relay versions use high quality sputtered ruthenium relays that exhibit excellent contact performance under low and medium level switching conditions. For general purpose applications that also require higher power handling, the range of electro-mechanical relays provides an ideal solution.

We also offer mating cables and connectors for these modules to ensure speedy and successful system integration. We stand behind our products with a three-year warranty.
