Frequently Asked Questions (FAQ)

• What is the difference between the -01 and -02 connector options?
  The 330103-00-05-10-01-05 includes a connector protector for added durability in harsh environments, while the -02 option omits the protector.
• Can I use this 1.0 meter probe with a 5 meter Proximitor?
  No, always match probe and Proximitor cable lengths for proper impedance and calibration.
• Is this probe suitable for axial thrust measurements?
  Yes, the 8 mm form factor works for both radial vibration and axial position monitoring.
• Does the connector protector rotate during installation?
  The ClickLoc design allows secure locking without cable twisting.
