Frequently Asked Questions

• Q: Why choose 0.5 meter cable length?
  A: Shortest cable provides lowest resistance (7.45 Ohms) and best signal strength. Use 0.5m when your proximitor mounts immediately adjacent to the probe. Add extension cables if longer reach needed.
• Q: Can I add extension cable to this 0.5m probe?
  A: Yes. Total system length (probe cable + extension) must match your proximitor calibration. Example: 0.5m probe + 4.5m extension = 5.0m system. Do not exceed the total length printed on your proximitor label.
• Q: What is a reverse mount probe?
  A: Reverse mount probes install from inside the machine casing outward. Use for thrust position measurement, limited access areas, or when standard outside mounting is not possible due to space constraints.
• Q: Can I use this probe in hazardous locations?
  A: No. Option 00 means no hazardous location certifications. For hazardous areas (Class I, Div 2 or Zone 2), choose option 05 (multiple approvals) instead.
• Q: What is the advantage of ceramic tip for short cable probes?
  A: Alumina ceramic tip provides exceptional wear resistance and stable dielectric properties. It maintains performance in abrasive environments where standard PPS tips may wear prematurely.
