Technical Specifications

Note: Electrical parameters such as sensitivity, gap range, and frequency response are system-dependent and vary by installation configuration. DriveKNMS does not publish unverified specifications. Contact us with your system documentation for a compatibility assessment.

Solving the Discontinued Hardware Crisis

The PR6423 sensor family was designed for long-term integration into fixed monitoring architectures. Plants that installed EPRO CON Series systems in the 1990s and 2000s built their machinery protection logic around the specific signal characteristics of these sensors — linearity curves, sensitivity coefficients, and gap calibration data that are not interchangeable with modern alternatives without a full system re-qualification.

For a plant operating a gas turbine, steam turbine, or large centrifugal compressor train, the cost of a forced migration away from a functioning EPRO-based protection system is substantial. Engineering studies, new sensor brackets, conditioner replacement, DCS integration work, and mandatory functional safety testing can collectively exceed USD 500,000 per machine train. Against that figure, sourcing a verified replacement PR6423/13R-030 CON021 from DriveKNMS represents a fraction of the cost — and preserves the existing calibration baseline.

Condition & Reliability Assurance

DriveKNMS applies a 5-step quality assurance protocol to all obsolete and legacy parts before dispatch:

• Step 1 – Visual and Mechanical Inspection: Full examination of the sensor body, cable jacket, connector pins, and tip geometry. Any physical damage, corrosion, or deformation results in immediate rejection.
• Step 2 – Electrolytic Capacitor Assessment: For associated conditioning electronics, capacitor aging is evaluated. Sensors with integrated electronics are checked for ESR drift and leakage current.
• Step 3 – Pin and Connector Integrity: Connector contacts are inspected under magnification for oxidation, fretting corrosion, and mechanical deformation. Affected units are cleaned or rejected based on severity.
• Step 4 – Firmware and Configuration Verification: Where applicable, firmware version and factory configuration data are verified against known-good references.
• Step 5 – Functional Bench Test: Each unit is tested for basic electrical continuity and, where test fixtures are available, signal output verification against reference targets.

Key Features for System Maintenance

How do I know the part is genuine and not counterfeit?
All units sourced by DriveKNMS are procured through documented supply channels. Physical markings, date codes, and construction details are cross-referenced against known-authentic references. We do not sell parts that cannot be traced to a credible source. If you require additional authentication documentation, request it at the time of inquiry.

Should I buy more than one unit?
For any obsolete sensor installed in a critical protection application, holding a minimum of two spare units is standard practice. Given that the PR6423/13R-030 CON021 is no longer in production, availability on the secondary market will decrease over time. Procurement decisions made today carry significantly lower risk than emergency sourcing during an unplanned outage.

Can DriveKNMS source other EPRO CON Series parts?
Yes. DriveKNMS specializes in obsolete and hard-to-find industrial automation components. If you require other parts from the EPRO PR6423 family, CON Series conditioners, or associated MMS 6000 system components, contact us with your full part list.
