The NI SH68-68-EP is a 10-meter shielded digital cable engineered for high-integrity data transfer between National Instruments DAQ devices and signal conditioning accessories. Built with 68 conductors and dual 68-pin female SCSI 0.050 D-Type connectors, this cable delivers the noise immunity required in electrically challenging laboratory and industrial environments. Multilayer shielding protects against EMI and crosstalk, ensuring signal fidelity across mixed-signal applications.
