Ametek / VTI Instruments / VXI Technology SMP4002 High-Density Matrix Module

The Ametek / VTI Instruments / VXI Technology SMP4002 is a high-density matrix module that performs signal routing and switching within automated test systems. This 1 (4×36) 2-wire matrix operates as part of the SMIP II Series, a modular platform designed for VXIbus systems. The module handles switching voltages to 300 V ac/dc and currents to 2 A per channel, with maximum switching power ratings of 60 W dc and 125 VA. Path resistance remains below 500 mΩ, and insulation resistance exceeds 1×10⁹ Ω, ensuring signal integrity across configurations.
