Manager’s Insight

“For rotating equipment engineers who demand absolute data integrity, the 330171‑00‑94‑10‑02‑00 offers best‑in‑class RFI/EMI immunity and mechanical robustness. Its ClickLoc™ connector reduces installation time by 40% compared to standard connectors, and the 304 SST case withstands harsh industrial environments. I recommend this for high‑speed train monitoring where downtime is not an option.” — Senior Product Manager, Powergear X

• Paper mill rolls, cooling tower fans – reliable in wet environments.

Model Selection Guide – 330171 Family

• 330171-00-94-10-02-00 (this item): 1.0 m cable, 9.4 in case length, miniature ClickLoc™, 0 in unthreaded length – best for standard clearance installations.
  Choose if you need a compact, direct‑connect probe with PPS tip.
• 330171-00-32-05-01-CN – 0.5 m cable, 3.2 in case length, different connector option. Ideal for very confined spaces.
• 330171-00-40-05-02-00 – 0.5 m cable, 4.0 in case length, standard coaxial connector. Better for retrofit when extension cable already exists.

FAQ – Experience & Buying Guide

• What is the difference between -00-94 and -00-40 case lengths?
• The two‑digit code after the dash indicates overall case length in tenths of an inch. -94 = 9.4 in case, suitable for deep mounting holes. The -40 = 4.0 in case is for shallow bores.
• Can I use this probe with an older 3300 (non‑XL) system?
• Yes, the 330171‑00‑94‑10‑02‑00 is electrically compatible with all 3300 series proximitors. However, you will need the corresponding extension cable (e.g., 330130 series) with ClickLoc™ connector.
• What happens if the ambient temperature exceeds +177°C?
• The probe tip PPS material can withstand short spikes, but continuous operation above +177°C will reduce life. For higher temperatures, consider the high‑temp variant with different temperature classification (T2/T3).
• How do I verify correct gap without an oscilloscope?
• Use a digital voltmeter on the proximitor output. At 1.27 mm (50 mils) nominal gap, you should read approx -9.5 to -10.5 Vdc (with -24 V supply). Adjust until you reach the transducer’s midpoint voltage.
• Which extension cable part number matches this probe?
• Use 330130‑XX‐YY‐ZZ series with miniature coaxial ClickLoc™ (option ‑02). The total system length (probe + extension) should be 5 m or 9 m for optimal linearity.
