Performance Parameters The probe provides a stable analog voltage output proportional to the distance between the probe tip and the conductive target surface. The system achieves high linearity and temperature stability across the full operating range.
Material Composition
- Probe Tip: Polyphenylene Sulfide (PPS)
- Probe Case: AISI 303 or 304 stainless steel
- Cable: FEP insulated triaxial cable
- Connector: Gold-plated miniature coaxial ClickLoc
Structural Characteristics The probe has a 30 mm overall case length with zero unthreaded length. The shorter 0.5 meter cable length makes this variant suitable for installations where the Proximitor sensor is located close to the measurement point. The M10 × 1 metric thread provides standard mounting compatibility.
Working Principle The probe generates a high-frequency electromagnetic field at its tip. When a conductive target approaches, eddy currents are induced in the target material. The resulting change in the probe coil impedance is detected and converted into a DC voltage signal proportional to the gap distance by the Proximitor sensor.
Installation Requirements
- Install perpendicular to the target surface
- Use M10 × 1 threaded housing for precise depth adjustment
- Secure with locking nuts after positioning
- Verify gap voltage at -9 Vdc to -10 Vdc during commissioning
- Maintain proper shield grounding throughout the system
- Observe minimum cable bend radius specifications
Usage Precautions
- Must be paired with a 3300 XL Proximitor sensor and appropriate extension cable
- Target material must be ferromagnetic and free from plating or coatings that affect conductivity
- Keep probe tip clean and free from metallic debris
- Avoid installations where the cable is subject to repeated flexing beyond specifications
- The CN designation indicates regional certification compliance without altering technical performance
