Replacement & Compatibility FAQ
Q: Can I use a 330905 (8 mm) probe as a direct replacement for the 330903 (5 mm)?
A: Not directly. The 8 mm probe requires a matched 8 mm Proximitor driver. Swapping tip size requires changing the driver as well.
Q: Is the 330903-00-22-10-02-05 compatible with older 3300 (non-XL) systems?
A: The 3300 XL probe is backward-compatible with most 3300 series drivers, but sensitivity calibration should be verified. Contact our technical team for confirmation.
Q: What is the total system cable length?
A: Total cable length = probe integral cable (5 m) + extension cable. Standard system lengths are 5 m, 9 m, and 15 m. Ensure your Proximitor is matched to the total length.
Q: Do you supply ATEX/IECEx certified versions?
A: Yes. Please specify your certification requirement when requesting a quote.
Q: Can Konmask provide a Certificate of Conformance?
A: Yes, CoC and factory test documentation are available upon request for all OEM units.
