Bently Nevada 330705-02-18-10-02-00 3/8-24 Reverse-Mount Proximity Probe
A stocked 3/8-24 reverse-mount probe with a one-metre lead and standard ClickLoc connection.
Overview
330705-02-18-10-02-00 is the imperial reverse-mount probe option in the 3300 XL 11 mm system. Its fixed 02-18 geometry and 3/8-24 thread distinguish it from both the M10 reverse-mount version and the larger standard-mount cases.
The probe is one component of a calibrated 11 mm loop and must be matched to the extension cable and Proximitor Sensor.

FAQ
What is the key difference between 330705-02-18-10-02-00 and 330706-005-046-10-02-00?
The 330705 uses a 3/8-24 imperial reverse-mount thread, while the 330706 uses M10×1 metric geometry.
Can 330705-02-18-10-02-00 connect to a standard 8 mm Proximitor?
No. It belongs to the calibrated 3300 XL 11 mm system.
How is extension-cable length selected for 330705-02-18-10-02-00?
Subtract the one-metre probe lead from the connected five- or nine-metre Proximitor system length.
Does 330705-02-18-10-02-00 include agency approvals?
No. The final 00 code means approval is not required.
What mechanical information is essential when ordering 330705-02-18-10-02-00?
Confirm rear access, holder thread, fixed 02-18 geometry, insertion depth and cable-clearance route.
What should be tested after fitting 330705-02-18-10-02-00?
Verify gap voltage, linear response, waveform, scale factor, channel scaling and alarm or trip operation.
