Emerson Epro PR6423/002-030 CON021 Eddy Current Sensor
An M10 x 1 PR6423 probe with a 45 mm sleeve, adapter plug at 1 m, 8 m total cable and Lemo converter connection.
Product Overview
PR6423/002-030 is an 8 mm eddy-current sensor execution for non-contact shaft displacement and machinery-monitoring measurements.
Its ordering code defines an M10 x 1 thread, non-armored cable and a 45 mm sleeve length.
The code also retains the adapter plug at 1 m, 8 m total cable length and Lemo connector used with the approved converter.
Performance
Provides a 2 mm linear measuring range in the documented measurement chain.
Uses a nominal 0.5 mm initial air gap for the published response.
Supplies an ISO incremental scale factor of 8 V/mm under stated target conditions.
Supports radial and axial displacement, position, eccentricity and speed measurement duties.

- Speed measurement when configured in the documented PR6423 measurement system.
FAQ
Q01Can PR6423/002-030 replace PR6423/002-130?+
Not automatically. The fourth code position changes the adapter-plug execution, so the installed cable arrangement and converter connection must be checked.
Q02What should accompany a PR6423/002-030 quotation?+
Provide the full probe and converter labels, mounting drawing, target, cable route, hazardous-area requirement and current static gap record.
Q03Why is the adapter position important for PR6423/002-030?+
It defines the physical division of the calibrated chain and affects routing, service access and the approved converter connection.
Q04What installation damage is most important to inspect on PR6423/002-030?+
Check the PEEK tip, M10 x 1 thread, coaxial cable, adapter, connector and any point exposed to heat, chemicals or tight bending.
Q05How should PR6423/002-030 be accepted after exchange?+
Document static gap, dynamic signal, slow-roll behavior, scale, polarity, alarms and the full protection-channel test.
