  • Rear‑end ClickLoc miniature coaxial quick‑lock connector with protective sleeve
  • Standard machined metric thread allows direct screwing into machine housing mounting hole Working Principle: High‑frequency alternating current from Proximitor sensor flows through internal probe coil, generating alternating electromagnetic field around probe tip. When conductive metallic target approaches probe tip, eddy current is induced on target surface. The eddy‑current consumes magnetic‑field energy, changing equivalent impedance of probe coil. Proximitor circuit converts impedance variation into DC output voltage strictly proportional to physical gap between probe tip and target surface. Static displacement and dynamic vibration waveform can be captured through this voltage signal. Installation Requirements:
  • Mount probe perpendicular to measured rotating shaft target surface, keep mounting angle deviation less than 1‑degree
  • Screw probe into M10 × 1 tapped mounting hole on bearing housing; do not over‑torque during screwing process
  • Adjust static working gap to 1.27 mm recommended setting before machine startup
  • Connect probe ClickLoc connector finger‑tight until audible click sound appears, install matching connector protector
  • Keep total system length including probe cable plus extension cable strictly match Proximitor nominal system length
  • Probe tip must maintain full clearance from shaft surface, avoid mechanical collision during rotation
  • Keep probe cable away from high‑voltage power cables, maintain minimum 150 mm separation distance
  • Fix cable with cable clamps to avoid cable pulling stress transferred to probe body Usage Notes:
  • Do not scratch, impact or deform probe tip polymer surface, any tip damage will destroy calibration performance
  • Strictly forbid cutting or shortening factory‑integrated probe cable on‑site
  • Only use factory‑matched 3300‑XL series extension cable and Proximitor sensor
  • Inspect connector protector installation status periodically under heavy‑vibration environment
  • Prevent oil, water and corrosive medium invading connector contact surface
  • Perform gap‑voltage check during each unit overhaul cycle, verify transducer loop health status
