  • Rear‑mounted ClickLoc miniature coaxial quick‑lock connector without external protective sleeve
  • Metric thread structure for direct installation into machine housing tapped hole Working Principle: Proximitor sensor transmits high‑frequency excitation signal to probe internal coil, generating alternating magnetic field at probe tip. Eddy current is induced on surface of nearby conductive metallic target, consuming magnetic‑field energy and changing probe coil impedance. Proximitor circuit converts impedance variation into DC output voltage linearly corresponding to physical gap between probe tip and shaft target surface, realizing static position and dynamic vibration signal acquisition. Installation Requirements:
  • Install probe strictly perpendicular to rotating shaft target surface, angular offset cannot exceed 1‑degree
  • Screw probe body into M10 × 1 tapped hole on bearing housing, avoid excessive tightening torque
  • Adjust static gap to 1.27 mm before unit commissioning
  • Fasten ClickLoc connector by finger‑tight rotation until audible click locking feedback
  • Ensure total length sum of probe cable and extension cable matches Proximitor factory‑calibrated system length
  • Guarantee sufficient clearance between probe tip and rotating shaft to eliminate collision risk
  • Separate signal cable from high‑voltage power wiring with minimum 150 mm clearance
  • Apply cable clamps to support cable, eliminate pulling tension acting on probe housing Usage Notes:
  • Probe tip polymer surface must avoid mechanical impact, scratch and abrasive particle erosion
  • Do not cut or modify factory‑integrated probe cable length on‑site
  • Only deploy genuine 3300‑XL matched extension cable and Proximitor sensor
  • Since this model excludes connector protector, take extra precautions to prevent connector pin contamination and physical damage
  • Keep connector region away from machine oil, water vapor and corrosive chemical vapors
  • Verify probe gap‑voltage reading during each overhaul cycle to validate transducer loop integrity
