Replacement & Compatibility FAQ
Q: Can I use a 330106-05-30-10-02-00 in place of the 330106-05-30-10-12-00?
A: Yes — the only difference is cable length (2m vs 5m). Electrical performance is identical.
Q: Is the 330106 compatible with the 3500 Series monitors?
A: Yes, with the appropriate 3500/42 Proximitor module and correct driver configuration.
Q: Can third-party probes (Epro, Metrix) replace this unit?
A: Functionally possible, but requires driver recalibration and gap voltage verification. OEM replacement is recommended for critical machinery.
Q: What is the standard gap voltage for this probe?
A: −10.0 VDC ± 0.5 VDC at the nominal 1.0 mm (40 mil) gap on AISI 4140 steel target.
Q: Do you provide ATEX-certified units?
A: Yes. Please specify your hazardous area classification when ordering.
