We verify every sensor on a calibrated bench: scale factor, linearity, and gap voltage measured against manufacturer specifications. Units that deviate are not shipped. Printed test report with serial number and measured values included. Genuine EPRO. 12-month warranty. Ships within 24h.
Genuine vs. aftermarket — what is the difference?
Genuine {vendor} sensors use proprietary coil winding, calibrated magnetic materials, and individual sensitivity measurement. Aftermarket clones can deviate 15-30% from specification — enough to miss a fault or false-trip a machine.
What should I check before installation?
Inspect the target surface for pitting or runout. For eddy-current probes, the target must be clean and at least 2x the probe tip diameter. Verify bracket rigidity. Set gap voltage with a meter before tightening. Verify output at the proximitor after installation.
How do I verify compatibility?
Match the full part number on your existing sensor label. {vendor} encodes probe diameter, thread type, cable length, and connector style in the part number. A photo of your existing label allows our engineers to confirm within 4 hours.
