Selection Guide
Use the table below to identify the correct PR6424 converter variant for your application:
- Cable Length: /010 = 1 m | /014 = 1.4 m | /020 = 2 m | /050 = 5 m
- Gap Range: -140 = standard 0–14 mm measurement range
- Output Type: CON021 = current output (4–20 mA); CON011 = voltage output
- Hazardous Area: Specify ATEX / IECEx zone requirements at time of order
- Tip Diameter: Confirm probe tip size matches target shaft material and gap

Replacement & Compatibility FAQ
Q: Can I use a PR6424/010-140 CON021 in place of the /014-140 variant?
A: Yes, if the shorter cable length (1 m vs 1.4 m) is acceptable for your installation. The converter electronics are identical.
Q: Is the CON021 output compatible with a 4–20 mA PLC analog input card?
A: Yes. The CON021 suffix denotes a standard 4–20 mA current loop output, compatible with all major PLC analog input modules.
Q: Do you supply ATEX-certified versions?
A: Yes. Please specify your zone classification (Zone 1 / Zone 2) and gas group when requesting a quote.
Q: What is the lead time for the PR6424/014-140 CON021?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is typically 4–8 weeks from Emerson. Contact us for current availability.
Q: Can Konmask.com provide a datasheet or wiring diagram?
A: Yes — email support@konmask.com with your part number and we will send the official Emerson documentation.
