National Instruments SH68-8DB9 RS485 68-Pin VHDCI Cable

The high-performance National Instruments SH68-8DB9 RS4845 68-Pin VHDCI cable is intended to link NI DAQ hardware to external devices, particularly RS-485 interfaces. Offering adaptability in industrial and laboratory settings, the 1-meter cable has eight DB-9 ports at one end and a 68-pin VHDCI connection at the other. This cable is a useful tool for applications requiring dependable data gathering and control because it works with a variety of NI hardware families, including the NI 62xx (formerly M Series) and NI 63xx (formerly X Series).

Because the SH68-8DB9 RS4845 is made to transmit data in a noise-immune manner, it is perfect for high-performance applications where signal integrity is essential. In order to guarantee a safe and dependable connection between the DAQ hardware and external devices, it has an integrated 0.8 mm 68-pin VHDCI connector. The cable has a thin metallic shielding layer that conducts electricity to provide effective protection against electromagnetic interference (EMI), minimizing data loss and guaranteeing signal clarity. The overall noise performance is improved by this shielding, which covers the entire cable assembly and, in certain situations, particular groups of conductors.

The SH68-8DB9 RS4845 may also use twisted pair designs for differential analog input signals, pairing a positive (+) and negative (-) signal line. Because any common-mode signal is effectively cancelled by the differential analog-to-digital converter (ADC), this design helps reduce noise and interference. In addition, the cable might have drain or ground wires intertwined with signal wires to reduce noise and crosstalk even more and maintain excellent signal integrity in high-EMI settings.

Unshielded ribbon cables can be an inexpensive substitute in applications where crosstalk and electromagnetic interference are not an issue. But because of its sophisticated shielding and twisted pair design, the shielded SH68-8DB9 RS4845 cable is the best option for settings needing higher noise protection.
