Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the PR6423/015-000-CN CON021. Compatibility depends on your driver/conditioner and system configuration — consult our engineers before substituting.
- EPRO PR6423/010-000-CN CON021 — 1.0 m cable variant; same sensor head, shorter lead
- EPRO PR6423/020-000-CN CON021 — 2.0 m cable variant; extended reach for larger housings
- EPRO PR6424/015-000-CN CON021 — M16 thread variant; verify mounting bore before substituting
- Bently Nevada 330101-00-06-10-02-00 — 3300 XL series; functionally similar, requires 3300 driver
- Bently Nevada 330130-040-00-00 — 3300 NSv series; check gap voltage and sensitivity curve
- EMERSON CSI 6500 compatible probes — confirm driver compatibility with your CSI system
⚠ Always verify sensitivity (mV/mm), gap range, and driver compatibility before cross-referencing.
Why Choose the Original Model
- Factory-calibrated sensitivity: 8 mV/µm ±0.5% — no field recalibration required

- Differential expansion monitoring in power generation
- Rotor eccentricity and speed/phase reference (Keyphasor) setups
- Pump and motor bearing proximity measurement in petrochemical plants
- OEM machine builder integration for condition monitoring systems
System Compatibility
- EPRO MMS 6000 series vibration monitoring modules
- EPRO MMS 6350 proximity / position modules
- EPRO CON021 / CON041 extension cable systems
- Bently Nevada 3500 series (with sensitivity verification)
- Emerson AMS 6500 (confirm driver card compatibility)
- Third-party DCS/PLC systems accepting ±24 VDC powered eddy current probes
Selection Guide
Use the table below to select the correct PR6423 variant for your application:
- Cable length: Choose /010 (1 m), /015 (1.5 m), /020 (2 m), or /030 (3 m) suffix based on probe-to-driver distance
- Thread size: PR6423 = M14 × 1.5 | PR6424 = M16 × 1.5 — match your existing mounting boss
- Target material: Standard calibration is for AISI 4140 steel; request special calibration for titanium or aluminum targets
- Temperature class: Standard to 120 °C; high-temp variant available to 175 °C (specify at order)
- Connector type: CON021 = standard EPRO connector | CON041 = armored extension — specify based on environment

Replacement & Compatibility FAQ
Q: Can I use a PR6423/010-000-CN instead of the /015-000-CN?
A: Yes, if the shorter cable reaches your driver/conditioner. The sensor head and sensitivity are identical.
Q: Is the PR6423/015-000-CN compatible with Bently Nevada 3500 monitors?
A: Functionally similar, but Bently Nevada monitors are factory-calibrated for their own probe series. Sensitivity and gap voltage must be verified before substitution.
Q: Do you supply calibration certificates?
A: Yes. Original EPRO calibration documentation is available for all new units. Contact us to request.
Q: What is the warranty?
A: 12-month warranty against manufacturing defects. Damage from improper installation or electrical overstress is excluded.
Q: Can you source discontinued or long-lead EPRO part numbers?
A: Yes. Konmask.com specializes in sourcing hard-to-find industrial automation components. Submit your part number for a quote.
