Working Principle: Eddy current effect — the probe coil carries high-frequency current to generate an alternating magnetic field. The conductive target surface induces eddy currents, and the reverse magnetic field from these eddy currents alters the coil impedance. The proximitor converts this impedance change into a voltage signal proportional to the gap.

Installation Requirements:

  • The mounting hole must be machined with M10×1 internal thread
  • Probe cable + extension cable total length must equal the proximitor’s nominal system length (5-meter or 9-meter)
  • Set gap voltage to -10.0 VDC ± 0.2V
  • Apply moderate installation torque to avoid damaging the probe

Usage Precautions:

  • Confirm total system length matches the proximitor
  • Do not replace the probe while energized
  • Do not bend cables at right angles
  • Target surface must be conductive material, clean and free of oil
