(4) Cable protection tube (noise countermeasure)
If influence from noise is unavoidable, or further noise resistance is required, selecting a flexible
tube and running the signal cable through this tube is effective. This is also an effective
countermeasure for preventing the cable sheath from being cut or becoming worn due to cutting
chips.
A cable clamp (MS3057) is not installed on the detector side, so be particularly careful of broken
wires in applications involving bending and vibration.
