The NI SH68-68-EP is a 1-meter shielded digital cable terminated with 68-pin female SCSI 0.050 D-Type connectors on each end. It delivers reliable signal integrity for data acquisition and multifunction I/O applications by combining multilayer shielding with differentiated conductor gauging. The cable accommodates analog input pairs, digital twisted pairs, digital single conductors, and power distribution in a single interconnect, making it suitable for E Series, M Series, S Series, and B Series DAQ devices as well as signal conditioning accessories.
– Technical Specifications
• Cable Type: Shielded digital cable, 68 conductors
• Length: 1 meter
• Connector Type: Two 68-pin female SCSI 0.050 D-Type connectors
• Conductor Gauge: 28 AWG for individually shielded analog input pairs, digital twisted pairs, and digital single conductors; 20 AWG for +5 V lines
• Shielding: Multilayer construction for enhanced noise rejection
• DC Resistance (Digital Single Conductors): Typically 0.070 Ohms/ft at 20 °C
• Jacket Material: Fire-resistant plastic
– Key Features
• Differentiated conductor gauging optimizes signal fidelity across mixed-signal systems
• Individually shielded analog pairs minimize crosstalk and EMI coupling
• Multilayer shielding provides superior noise rejection in electrically noisy environments
• Impedance and capacitance specifications are defined for both analog and digital twisted pairs
• Time delay characteristics are specified for matched-pair integrity
• Dedicated 20 AWG power conductors support +5 V distribution
– Typical Applications
• Connection of NI DAQ devices to signal conditioning accessories
• Integration with SCXI systems and SCC portable conditioning modules
• Interfacing multifunction I/O modules with terminal blocks (screw and BNC)
• Laboratory data acquisition and test automation systems
– Compatibility & Integration
The cable is compatible with E Series (most 68-pin NI60xxE devices excluding DAQCards), M Series DAQ devices, S Series devices (except NI 6143), and B Series PCI devices. It connects to CB-68LPR, SCB-68, AT-MIO-16E-10, SC-204x series accessories, SCC and SCXI signal conditioning, and terminal blocks including TB-2705, BNC-2110, BNC-2120, and BNC-2190.
