Selection Guide
Use the following criteria to confirm the PR6423/01C-010 CON021 is the correct part for your application:
- Probe diameter: Must be 8mm EPRO-compatible probe (e.g., PR6423 probe series)
- Cable length: Confirm extension cable length matches system requirement (010 = 1.0m driver cable)
- Connector type: CON021 = 9-pin D-sub; verify rack/monitor connector pinout
- Supply voltage: Confirm –24 VDC supply is available at installation point
- Output range: Verify monitor input accepts –24 VDC bias with linear voltage output
- Temperature rating: Confirm ambient temperature at installation is within –35°C to +85°C

Replacement & Compatibility FAQ
Q: Can the PR6423/01C-010 CON021 replace a Bently Nevada 3300 XL proximitor?
A: In many cases yes, but output scaling and connector pinout must be verified. Contact us for a detailed cross-reference.
Q: What is the difference between CON021 and CON031?
A: CON021 uses a 9-pin D-sub connector; CON031 uses a different connector configuration. Verify your rack’s input connector before ordering.
Q: Is recalibration required after replacement?
A: When replacing with an identical OEM part in a matched system, recalibration is typically not required. Third-party equivalents may require gap and sensitivity verification.
Q: Do you supply the matching PR6423 probe and extension cable?
A: Yes. Contact us to order a complete probe system including probe, extension cable, and converter.
Q: What warranty is provided?
A: Konmask.com provides a 12-month warranty on all supplied units against manufacturing defects.
