Product Introduction
The Bently 330930-065-02-00 serves as the critical signal link. This extension cable connects the 8mm proximity probe to the transducer.
This industrial automation unit maintains strict impedance matching over 6.5 meters. Signal integrity remains stable despite harsh plant EMI environments.

Quality Control Process
We validate every replacement module for signal fidelity. First, a Fluke multimeter checks continuity and shield isolation. Open circuits fail immediately. Next, we verify capacitance against factory specs. Deviation indicates internal damage or moisture ingress. We then perform a high-voltage hipot test. This ensures insulation won’t break down under transients. Finally, we inspect connector strain relief. All units ship in anti-static shielding.

Replacement Pitfall Guide
❗ Never Splice This Cable. Cutting or soldering extensions destroys impedance matching. Signal reflections will corrupt your vibration waveform. Replace the entire assembly if short.
❗ Enforce Single-Point Grounding. Ground the shield at the monitor chassis only. Grounding at both ends creates a loop. You will see 60Hz noise in your data.
❗ Verify Cable Length Code. The “065” denotes exactly 6.5 meters. Swapping lengths changes system capacitance. Your gap voltage will drift without recalibration.
❗ Protect the Connectors. Keep mating surfaces clean and dry. Oxidation adds contact resistance. This causes intermittent signal loss during machine startup.
Keep these in mind and you’ll cut 90% of rework time.
