Selection Guide
Use the table below to select the correct PR6423 variant for your application:
- Probe cable length (XXX): 005 = 0.5 m | 010 = 1.0 m | 020 = 2.0 m
- Extension cable (YYY): 050 = 5.0 m | 100 = 10.0 m | 110 = 11.0 m | 150 = 15.0 m
- Target material: Steel (standard) — specify if stainless, titanium, or non-ferrous
- Conditioner: CON021 (standard) | CON011 (legacy) | CON031 (high-temp)
- Shaft diameter: PR6423 (8 mm probe) suits shafts ≥ 50 mm; use PR6424 for larger clearances

Replacement & Compatibility FAQ
Q: Can I use PR6423/010-110-CN with a Bently Nevada 3500/42M module?
A: Yes. The CON021 conditioner outputs a -24 VDC signal compatible with Bently Nevada 3500 series proximity inputs. Verify gap voltage setting (typically -10 VDC at nominal gap).
Q: What is the difference between CON021 and CON011?
A: CON021 is the current-generation conditioner with improved EMI shielding and wider temperature range. CON011 is the legacy version; both are signal-compatible but CON021 is recommended for new installations.
Q: Is the PR6423/010-110-CN suitable for high-temperature environments?
A: The probe is rated to +120°C. For applications above this, consider the PR6424 high-temperature variant or contact us for application engineering support.
Q: Can Konmask.com supply the complete probe-cable-conditioner kit?
A: Yes. We supply complete kits (probe + extension cable + CON021 conditioner) as well as individual components. Specify your requirement when ordering.
Q: Do you provide a warranty?
A: All units carry a 12-month warranty against manufacturing defects from the date of shipment. Warranty claims are processed within 5 business days.
