The extremely short 11 mm case length suits space-constrained installations within tight machinery casings. Its flush-mount design positions the tip directly at the casing surface for optimal gap control. The FEP cable insulation offers excellent resistance to oil, moisture, and chemical contaminants.

The integrated eddy current technology delivers high-resolution displacement readings. This sensor reliably detects early wear, imbalance, or misalignment. Consequently, operators reduce unplanned downtime and lower overall maintenance costs.

The 330101-00-11-10-02-05 integrates seamlessly with 3300 XL Proximitors and 3500 monitoring systems. Its intrinsic safety certification (Zone 0/1) makes it suitable for hazardous areas like refineries and chemical plants. Standardized connectors and components simplify spare parts management across multiple installations.
