National Instruments DB8F-Bare Wire-40A Switch Cable

The National Instruments DB8F-Bare Wire-40A (Part Number: 781092-02) is a specialized cable intended to link PXI signal insertion switch modules—more especially, the PXI-2512, PXIe-2512, PXI-2514, and PXIe-2514—to a range of applications. In industrial automation installations, it makes signal routing between instruments and devices-under-test (DUT) easier. This cable consists of several components, including a DB8F connector, thumbscrews for secure attachment, cable leg labels for easy identification, and eight unterminated wires for versatile connectivity.

The cable has eight shielded, 8AWG stranded, unterminated wires on one end that terminates with a DB8F connector. The DB8F-Bare Wire-40A cable is appropriate for industrial applications because of its maximum voltage rating of 50 VDC and 30 VACrms. A maximum of 40 A of current can be handled by each wire or pin. Nevertheless, it must not be linked to 115 or 230 VAC mains supply circuits (such as wall outlets). The cable is designed for indoor use only and operates within a temperature range of 0°C to 50°C. It can be safely stored in temperatures ranging from -20°C to 70°C. It complies with Pollution Degree 2 regulations and has a relative humidity operating range of 5% to 85%, non-condensing. With a weight of 1372 g (48.4 oz), the DB8F-Bare Wire-40A cable is sturdy and long-lasting, making it appropriate for use in harsh industrial settings. It is suitable for use at altitudes of up to 2,000 m. For a simple connection to the PXI signal insertion switch modules and the application, the DB8F-Bare Wire-40A cable has pinouts and pin assignments. Precise signal routing is made possible by the fact that every pin on the DB8F connection is associated with a particular channel or function on the switch modules.
