Description
The National Instruments SH68-C68-S Cable is a high-quality interconnect solution featuring a 68-Pin VHDCI to 68-Pin .050 Series D-Type Cable design, ensuring compatibility with a range of devices including NI-73xx Motion Controllers, PXI Motion Controllers, PCI Controllers, and the UMI-7764 interface. Additionally, it can be used with PXIe-6738 and PXIe-6739 analog output devices within an NI-6723 system.
This shielded cable includes 34 twisted pairs of wire to minimize interference, providing a stable connection critical for precise motion control applications. The connectors are a 68-pin VHDCI male on one end and a 68-pin 0.50 Series D-type on the other, ensuring secure and reliable connections.
With a time delay of 1.45 +/-0.05 ns/ft and a differential impedance of 132 ohms +/-10 ohms @ TDR, the cable is designed for high-performance applications. The maximum mutual capacitance is 12.5 pF/ft, which helps to maintain signal integrity over the cable’s length.
The SH68-C68-S Cable comes in three different lengths to accommodate various system configurations: 0.5 m (186381-0R5), 1 m (186381-01), and 2 m (186381-02), providing flexibility and convenience for system designers and installers.
