Performance Parameters The probe provides a scaled analog signal from -1 to -17 Vdc proportional to gap. The system delivers advanced performance with excellent linear range, accuracy, and temperature stability. The wide temperature range accommodates extreme industrial environments.
Material Composition
- Probe Tip: Polyphenylene Sulfide (PPS)
- Probe Case: AISI 303 or 304 stainless steel
- Cable: Triad shielded coaxial construction
- Connector: Gold-plated miniature coaxial ClickLoc
Structural Characteristics The probe features a 30 mm overall case length with zero unthreaded segment. The M10 × 1 metric thread provides standard mounting. The 1.0 meter factory-attached cable uses triad shielded construction for superior noise immunity. The CN suffix signifies manufacturing with relevant local compliance markings.
Working Principle The probe generates an electromagnetic field at its tip. When a conductive target is present, eddy currents are induced in the target material. The resulting impedance change in the probe coil is detected and converted by the Proximitor sensor into a DC voltage directly proportional to the physical gap distance.
Installation Requirements
- Mount the probe perpendicular to the shaft surface
- Use the M10 × 1 thread for depth adjustment with maximum 15 mm engagement
- Tighten locking nuts to prevent vibration-induced shifting
- Verify gap voltage at -9 Vdc during setup
- Maintain shielding continuity from probe to Proximitor
- Use proper cable routing with adequate bend radius
Usage Precautions
- The probe is a passive sensor driven by the Proximitor interface
- Must be used with compatible 3300 XL extension cables and Proximitor sensors
- The CN suffix indicates regional compliance without altering technical performance
- Keep the probe tip free from metallic debris and contamination
- Do not exceed the maximum cable length without proper signal conditioning
- Connector protectors are recommended for all installations
