Performance Parameters The armored cable provides superior mechanical protection against abrasive debris and industrial fluids. When integrated into a complete 3300 XL system, the probe provides a stable linear output highly resistant to temperature cross-sensitivity and electromagnetic interference.
Material Composition
- Probe Tip: Polyphenylene Sulfide (PPS)
- Probe Case: AISI 303 or 304 stainless steel
- Cable: FEP insulated triaxial cable with stainless steel fluid-tight armor
- Connector: Gold-plated miniature coaxial ClickLoc
Structural Characteristics The 50 mm case length provides substantial mounting depth. The 1.0 meter cable features stainless steel fluid-tight armor for protection in harsh environments. The ClickLoc connector includes a connector protector for enhanced environmental sealing.
Working Principle The probe generates a high-frequency RF field that induces eddy currents in a conductive target. The resulting impedance change is converted by the Proximitor sensor into a DC voltage proportional to the gap distance. The armored construction ensures signal integrity in physically demanding installations.
Installation Requirements
- Mount perpendicular to the shaft axis
- Use M10 × 1 thread for secure installation
- The armored cable requires appropriate fittings for passage through machine housings
- Set gap to achieve -9 Vdc to -10 Vdc output
- Ensure armor continuity is properly grounded if required
- Use compatible 3300 XL extension cables to match Proximitor system length requirements
Usage Precautions
- The armored cable adds rigidity; observe minimum bend radius carefully
- Ensure armor termination does not compromise connector sealing
- Verify compatibility with extension cable armor types when connecting
- Do not use in environments exceeding the temperature rating of the armor material
- Regular inspection of armor integrity is recommended in abrasive environments
