Measures shaft motion without mechanical contact.
Product Identification
PR6423/03R-012-CN is a complete ordering execution in Emerson EPRO’s PR6423 family of 8 mm eddy-current sensors.
The PR6423 family provides non-contact shaft measurement for displacement, position, eccentricity and speed, with a published 2 mm measuring range.
The full /03R-012-CN suffix is preserved without assigning unverified meanings to each segment; exact mechanical, cable and connector details must be confirmed from manufacturer ordering data and the installed label.

Functions
Supports the displacement, position, eccentricity and speed uses documented for PR6423.
Operates within the published 2 mm range when installed with the approved gap and converter.
Keeps every suffix segment visible to prevent a near-match substitution.
Applications
- Exact-execution replacement in an existing PR6423 measurement chain.
- Radial shaft vibration or axial position measurement on rotating machinery.
- Eccentricity and speed-related sensing with approved target geometry.
- Revision-controlled sensor inventories where cable and connector execution matter.
Lifecycle
- Record the complete sensor and converter labels, mounting geometry, gap and cable route.
- Protect the sensing tip, thread and cable from impact, contamination and tight bends.
- Confirm exact mechanical and connector execution before disturbing the installed loop.
- After installation, verify bias voltage, scale factor, polarity, trend and alarm response.
FAQ
Q01What should accompany a PR6423/03R-012-CN enquiry?
Send the complete sensor and converter labels, probe mounting photographs, cable and connector details, target data, quantity and destination.
Q02Can PR6423/03R-012-CN be replaced by PR6423/016-030?
Not from the shared PR6423 family alone. Compare the complete suffix, mechanical execution, cable, connector and approved converter.
Q03Why is each PR6423/03R-012-CN suffix segment retained?
Those segments define the ordering execution; preserving them avoids borrowing incompatible mechanical or cable details from a nearby model.
Q04What field evidence helps diagnose an unstable PR6423/03R-012-CN signal?
Record static gap, bias voltage, target condition, connector state, cable routing, grounding and converter supply before parts are changed.
Q05What proves PR6423/03R-012-CN is ready for service?
Confirm exact identity, secure mounting, correct gap, stable bias, correct scale factor and passed trend and alarm-channel tests.
