Model Number Decoded

Each part of the model number tells you key features:

330104: Base 8mm probe with M10x1 thread and armored design
00: Unthreaded length (0mm)
20: Overall case length (200mm)
10: Total cable length (1.0m/3.3ft)
02: Mini coaxial ClickLoc connector (standard cable)
05: Approvals (CSA, ATEX, IECEx)

Installation Basics

Use with a -24Vdc power supply and 10kΩ load.
Set the probe gap at 1.27mm (50 mils) from AISI 4140 steel.
Avoid voltages above -23.5Vdc to keep full measurement range.

Works With

Only compatible with 3300 XL 8mm components (probe, extension cable, proximitor). Accuracy may drop if used with non-AISI 4140 steel targets.

Certified For Safety

Complies with CSA, ATEX, and IECEx standards – trusted for safe use in industrial environments.
