Replacement & Compatibility FAQ
Q: Can I use the 330103-01-06-05-02-05 with my existing 3300 XL proximitor?
A: Yes — provided your proximitor is the 3300 XL 5 mm model (330130 series). Mixing 5 mm probes with 8 mm proximitors will result in calibration errors.
Q: Is this probe interchangeable with the older 3300 (non-XL) series?
A: The 3300 XL probes are not directly interchangeable with legacy 3300 probes due to different sensitivity curves. A full system recalibration is required if mixing generations.
Q: What is the difference between the -02-05 and -02-00 suffix?
A: The -05 suffix denotes a BNC connector termination on the cable end; -00 indicates a bare/flying lead. Ensure your junction box or monitor input matches.
Q: Do you supply calibration certificates?
A: Yes. Factory calibration certificates are available for new OEM units. For surplus stock, we provide in-house test reports. Contact us to request documentation before purchase.
Q: Can this probe be used in hazardous (Ex) areas?
A: The 330103 series carries ATEX and FM approvals for use in Zone 1/Division 1 hazardous areas when installed with the appropriate certified barrier or Zener barrier. Verify the specific approval suffix on your unit.
