Buyer’s Selection Guide

• Verify the total system length (Probe + Cable) matches the Proximitor calibration (e.g., 5m or 9m).
• Choose the 27490-0370-00 when high flexibility is needed in narrow conduits.
• Select armored versions only if the cable is exposed to extreme mechanical impact.

Frequently Asked Questions (FAQ)

• Question: Is the 27490-0370-00 interchangeable with non-XL cables?
  Answer: No, XL series cables have specific electrical properties for XL Proximitors to ensure accuracy.
• Question: What happens if the cable length is modified in the field?
  Answer: Modifying length changes capacitance, which will invalidate the system calibration and linearity.
• Question: How does this cable handle electromagnetic noise?
  Answer: Its triaxial shield provides a continuous guard that isolates the signal from heavy motor interference.
