Bently Nevada 84661-30 Interconnect Cable — Proximity System Signal Conduit | 3300 XL Series Platform
Engineering Background
The Bently Nevada 3300 XL proximity measurement system is the industry benchmark for continuous shaft vibration, position, and speed monitoring in rotating machinery. The interconnect cable is the critical signal-path link between the proximity probe and the proximitor/extension cable assembly, ensuring low-noise, impedance-matched transmission of eddy-current displacement signals in demanding plant environments.
Product Positioning
The 84661-30 is an OEM-specification interconnect cable engineered for the Bently Nevada 3300 XL proximity system. It is the preferred replacement and spare-parts choice for reliability engineers and instrumentation teams maintaining turbines, compressors, pumps, and other critical rotating assets where signal integrity directly impacts machinery protection system performance.

System Architecture & Signal Flow
In the Bently Nevada 3300 XL proximity measurement chain, the signal path is:
Proximity Probe → Interconnect Cable (84661-30) → Extension Cable → Proximitor/Seismic Transducer → 3300 Monitor Rack
The 84661-30 interconnect cable occupies the first link in this chain, connecting the probe tip assembly to the extension cable. Its impedance and capacitance characteristics are factory-matched to the 3300 XL proximitor driver circuit, ensuring the system’s ±200 mV/mil (±7.87 V/mm) output sensitivity is preserved across the full measurement range.
Sourcing & Quality Verification

Technical FAQ
Q: Is the 84661-30 compatible with the older Bently Nevada 3300 (non-XL) system?
A: The 84661-30 is specified for the 3300 XL platform. Compatibility with legacy 3300 systems depends on connector and impedance matching — contact our technical team to confirm before ordering.
Q: Can this cable be used with third-party proximitors?
A: It is designed for Bently Nevada OEM proximitors. Use with third-party drivers may affect system calibration and is not recommended without engineering review.
Q: What is the standard lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time varies by sourcing channel — typically 2–6 weeks. Contact us for current availability.
Q: Do you provide a datasheet or wiring diagram?
A: Yes. Bently Nevada 3300 XL system documentation is available upon request. Contact support@konmask.com.
Q: Is this a new or refurbished unit?
A: Stock condition is confirmed at time of order. Both new and certified-refurbished units may be available — specify your requirement at inquiry.
