Frequently Asked Questions

• • Q1: Why choose 5 meter cable instead of extension cable?
    A: Fewer connections mean higher reliability. One continuous cable reduces signal loss and failure points.
  • Q2: What does CN approval mean?
    A: Country specific approvals. Check your local hazardous area requirements. May include ATEX, IECEx, or other standards.
  • Q3: Can I cut the cable to shorter length?
    A: No. Cutting changes impedance and calibration. Order correct length from factory.
  • Q4: What is the linear measurement range?
    A: About 0.25 mm to 2.3 mm (10 to 90 mils) with standard Proximitor. Best at 1.27 mm (50 mil) gap.
  • Q5: How to test if probe is working?
    A: Connect to Proximitor and power. Move a steel target near tip. Output voltage should change smoothly.

• • Q6: Field tip: How to protect cable near hot surfaces?
    A: Use heat shield or ceramic sleeves. Keep cable away from direct contact with pipes above 177°C.

• Buying Guide & Tips
  Pick 330172-00-08-50-02-CN when you need a short 0.8 inch case and long 5 meter armored cable. Great for remote panels. Avoid extension cables – simpler setup. CN approval suits many international sites. We offer 12-month warranty and ship within 12-24 hours via FedEx, UPS, DHL.
