Emerson PR6424/003-130 16 mm Eddy Current Sensor
A non-contact large-shaft sensor configured without armor or adaptor plug and with an 8 m LEMO-ended cable.
Product Overview
PR6424/003-130 is an Emerson PR6424 16 mm eddy current sensor for non-contact measurement on large ferromagnetic shafts. The family supports radial and axial dynamic displacement, position, eccentricity and speed or key measurements.
The official order matrix decodes the submitted execution as M18 × 1.5 thread, no armored cable and Cx length code 3 at 70 mm. Suffix 130 selects no adaptor plug, an 8 m total cable and a LEMO cable end.
The sensor must operate with the approved converter and target material. Gap, extension components, converter calibration and hazardous-area approval are system-level decisions rather than properties of the probe label alone.
Performance
Non-contact shaft measurement
Observes displacement or position without mechanical contact with the rotating target.
Large-shaft application
Uses the 16 mm sensor family intended for ferromagnetic shafts at least 80 mm in diameter.
Dynamic and static response
Supports position and vibration ranges defined for the matched PR6424 measurement chain.
Harsh-machine construction
Uses a stainless-steel sleeve and PTFE cable with published pressure and vibration resistance.

About IndustryParts
https://www.industryparts.com/The full sensor suffix controls mechanical and cable fit
IndustryParts keeps the PR6424 thread, body length, cable construction, connector and converter evidence together before a proposed sensor is released.
System Integration
Verify the complete chain
Match sensor, cable end, converter model and target material before setting the operating gap.
Protect the unarmored lead
Route the 8 m PTFE cable with appropriate support, bend radius and separation from damage sources.
Establish calibrated response
Set the approved gap and verify bias, travel and dynamic response with the receiving monitor or converter.
Applications
Large rotating shafts
Measuring vibration and position on turbines, compressors, pumps and fans.
Axial or radial observation
Supporting approved displacement geometry with the matched converter.
Speed or key reference
Providing a non-contact reference signal where the mechanical arrangement is validated.
FAQ
What mechanical execution is encoded by PR6424/003-130?
The 003 fields specify M18 × 1.5 thread, no armor and the 70 mm Cx length code.
What cable execution is encoded by PR6424/003-130?
The 130 suffix selects no adaptor plug, 8 m total cable and a LEMO end.
Can PR6424/003-130 be used with any eddy-current converter?
No. Converter type, calibration, range and approval must be compatible with the PR6424 measurement chain.
What target evidence should accompany PR6424/003-130?
Provide shaft material, diameter, surface condition, measurement direction, expected travel and installed gap.
What proves PR6424/003-130 is ready after installation?
A stable bias or gap value, verified travel, correct scaling and the required dynamic or speed test complete the record.
