(3) 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.
A cable clamp (MS3057) is not installed on the detector side, so be particularly careful of
broken wires in applications involving bending and vibration.
