• 02: Miniature ClickLoc coaxial connector, standard cable
• 05: Agency approval = Multiple Approvals (CSA/ATEX/IECEx)

Key Specifications

• Cable Length: 5.0 meters (16.4 feet)
• Length Tolerance: +20%, -0%
• Thread Size: 3/8-24 UNF
• Maximum Thread Engagement: 0.563 inch
• RPROBE at 5.0m: 8.73 ± 0.70 Ohms

Frequently Asked Questions

• Q: Why must 5m probe be used with 5m Proximitor only?
  A: The 5m probe has specific resistance (8.73 Ohms) calibrated for 5m Proximitor Sensor. Using with 9m proximitor or adding extension cables will cause measurement errors and invalidate hazardous area certifications.
• Q: What approvals does option 05 include?
  A: Multiple Approvals include CSA (North America), ATEX (Europe), and IECEx (international) for global hazardous location use. Suitable for Class I, Zone 0, Zone 2, and Division 2 areas.
• Q: What does +20%, -0% length tolerance mean?
  A: The cable may be up to 20% longer than 5.0m but never shorter. Actual length could be 5.0m to 6.0m. This accommodates manufacturing variation while maintaining calibration.
• Q: What is a reverse mount probe?
  A: Reverse mount probes install from inside the machine casing outward. Use for thrust position measurement or when standard outside mounting is not possible due to space constraints.
• Q: What is the advantage of ceramic tip for hazardous locations?
  A: Alumina ceramic tip provides excellent wear resistance and dielectric properties. It maintains performance in harsh industrial environments where standard PPS tips may degrade.
