Solution
To ensure the specified Electromagnetic Compatibility (EMC) performance, each NI DAQ product has its own specified maximum wire or cable length between a sensor and the NI DAQ Device I/O connector. Always refer to the NI DAQ hardware User Manual/Guide documents.
For example, the
PXIe-4309 User Manual mentions that the length of all I/O cables must be no longer than 3m.
When there are no specifications related to the maximum cable length for a certain NI DAQ device, it means that the EMC performance will not be affected by this factor. However, it is recommended to consult with the manufacturer of the sensor, as the length of the cable may not only affect the NI DAQ device, but it can also skew the true value of the measurement depending on the sensor.
