EPRO PR6423/006-131
Product Introduction
The EPRO /006-131 serves as a precision eddy current sensor for rotating machinery. This industrial automation unit tracks relative shaft motion with high fidelity for critical protection systems.
This replacement module delivers a standard 8 V/mm sensitivity across a ±1mm linear range. It is factory-calibrated to 42CrMo4 steel to ensure immediate installation readiness.

Quality Control Process
Every replacement module starts with coil resistance verification using a Fluke multimeter. We confirm factory tolerances before proceeding. Next, we test linearity on a precision micrometer stage. Deviations beyond ±1% FS trigger immediate rejection. Thermal soak testing follows at 180°C to validate insulation integrity. Finally, we inspect the M10 threads for damage. All units ship in anti-static shielding.
Replacement Pitfall Guide
❗ Match the前置器 (Conditioner) Exactly. This probe is part of a calibrated system. Connecting it to a mismatched conditioner (e.g., using a CON011 with a PR6424 calibration) destroys measurement accuracy. Verify your existing conditioner model first.
❗ Respect the 1.5mm Rated Gap. The nominal installation gap is 1.5mm. A 0.5mm offset causes significant amplitude errors at full scale. Do not guess this setting; use a feeler gauge or voltage method.
❗ Check Thread Specification. The M10 x 1.0 thread is metric fine-pitch. Cross-threading in aluminum housings destroys the mount instantly. Use a thread gauge and hand-start carefully.
❗ Mind the Target Material. This probe is calibrated for 42CrMo4 steel. Measuring non-standard alloys or thin targets requires recalibration. Verify your shaft material matches the calibration standard.
Keep these in mind and you’ll cut 90% of rework time.
