Description
The Bently Nevada 330130-040-01-CN is a high-performance extension cable designed to bridge the gap between a 3300 XL proximity probe and a 3300 XL Proximitor sensor. This specific configuration features a 4.0-meter length, which, when paired with a 1.0-meter probe, creates the industry-standard 5.0-meter total system length required for accurate vibration and position monitoring.
In critical rotating machinery applications, the extension cable is often the most vulnerable link in the signal chain. We maintain stock of these -CN (Chinese regulatory compliant) cables to ensure that global plant operators can replace damaged or “noisy” cables without waiting for standard factory lead times.

Operational Insights & Field Application
How does the stainless steel armor (-01 option) affect your installation? In field deployments at petrochemical refineries, we have observed that unarmored cables are frequently crushed or melted during routine maintenance. The SST armor provides essential mechanical protection against hot steam pipes and heavy foot traffic, though it does make the cable slightly less flexible.
The ClickLoc connectors on this cable are engineered for a “locking” fit, but they are not waterproof. This is a critical design choice: the gold plating ensures low contact resistance, but moisture ingress will ruin the signal.
Well, technically this is a 4.0-meter cable, but don’t underestimate the math—you must use this with a 1.0-meter probe to reach the 5.0-meter system requirement of your Proximitor. If you use a 4.0-meter cable with a 0.5-meter probe, your calibration will be off by 10%, leading to incorrect vibration readings in your DCS.
In my experience, the most common failure point is at the transition between the coaxial cable and the connector. Honestly, if you are pulling this cable through conduit, never pull by the connectors. Use a pull-sock or tape the armor to the pull-wire; otherwise, you’ll stretch the internal dielectric and change the cable’s capacitance, rendering it useless for precision monitoring.
Global Trade, Shipping, and Logistics Optimization
Shipping precision coaxial components across borders requires meticulous documentation to ensure the fastest possible transit.
Customs & Regional Compliance
The -CN suffix denotes compliance with NEPSI/CCC standards for the Chinese market. We classify this hardware under HS Code 8544.20.00 (Coaxial cable and other coaxial electric conductors). We provide a full digital and physical document set—Commercial Invoice, Packing List, and Certificate of Origin (COO)—to ensure the shipment clears customs without being held for “technical verification.”
Logistics and Transit
-
Protection: Every cable is coiled to its factory-spec bend radius and sealed in a moisture-barrier ESD bag. We over-box with rigid internal supports to prevent the armor from kinking during transit.
-
Air Freight: We exclusively utilize DHL Express and FedEx International Priority. For these high-precision instruments, air freight is the only way to minimize exposure to the extreme vibrations and moisture found in sea transit.
-
Incoterms: Standard delivery is FCA (Free Carrier) or CIP (Carriage and Insurance Paid to).
Trade Finance
To facilitate international procurement, we accept Telegraphic Transfer (T/T). For emergency plant outages, we can provide “Priority Release” upon verification of the bank SWIFT copy, ensuring the cable leaves our warehouse on the next available flight.
Frequently Asked Questions
Can I cut this cable to a shorter length if it’s too long?
No. Absolutely not. The length of the cable is part of a tuned LC circuit. Cutting it will change the capacitance and inductance, making it impossible for the Proximitor to accurately calculate the gap.
What is the benefit of the -CN version?
The -CN version carries specific certifications required for installation in hazardous areas within China. Electrically and mechanically, it is identical to the standard 330130-040-01, meaning it is safe to use in any global 3300 XL system.
Do I need a connector protector for this cable?
If the connection between the probe and the extension cable is located in an area with oil, water, or high humidity, a connector protector is mandatory to prevent signal attenuation.
Does your current project require a full 5-meter system, or are you just replacing the extension segment?
