National Instruments SA-413T Triaxial Adapter

The National Instruments SA-413T (Part Number: 784000-01) Triaxial Adapter is an essential component used to provide triaxial cable connectivity with PXIe-4138 and PXIe-4139 Source Measure Units. The SA-413T provides enhanced signal integrity along with proper grounding for very accurate signal measurement, thereby making it indispensable in the testing environment of high-performance applications.

The SA-413T is designed for seamless integration, directly connecting to the PXIe-4138/4139 modules through its two triaxial connectors, which are MIL-STD-348A standard, alongside a two-position screw terminal. In addition, it includes a specific pinout for Output HI, Guard (inner shield), Sense HI, Sense LO, Output LO, and Chassis Ground (outer shield), ensuring accuracy and stability that might be required within such an extensive array of test applications.

The SA-413T is designed for operation inside of tight electrical limits for the most robust levels of safety and reliability. Supporting up to 60 V DC or 42 V RMS relative to earth ground with a HI/LO current capacity of up to 3 A, this also includes a very rugged isolation with a continuous isolation voltage of up to 60 V DC and withstand ratings as high as 1,000 V RMS. These features protect both the SA-413T and connected equipment from possible electrical hazards.

Compact and lightweight, the dimensions of the SA-413T are 7.4 cm x 8.9 cm x 1.9 cm, making it easy to install; it weighs 119 grams. The SA-413T is designed to function in extreme conditions: survivable from 0°C to 55°C in operating temperature, between 10% and 90% of relative humidity, and shock up to 30 g with random vibrations within specified limits.

Compliance with the industrial standard further seals the SA-413T for reliability. Among these are safety certifications inclusive of IEC 61010-1, EN 61010-1, adherence to EMC regulations that ensure a minimum quantity of electromagnetic interference during operations, and following environmental directives such as RoHS and WEEE, showing concern by National Instruments for sustainability.

From advanced research labs to industrial testing, the SA-413T is an indispensable tool for applications requiring high-accuracy electrical measurements. It is versatile in design, rigorously compliant, improves system performance, and makes sure that safety, reliability, and environmental responsibility are ensured.
