The Bently Nevada 330730-040-00-CN is a specialized extension cable from the trusted 3300 XL series. This model measures 4.0 meters (13.1 feet) in length. It connects the 3300 XL 11 mm probe to the Proximitor Sensor for vibration monitoring. The distinguishing feature of this version is the country-specific connector option (code CN). This configuration meets regional electrical and mechanical standards for specific markets.
This cable uses a 75 Ω triaxial design with fluoroethylene propylene (FEP) insulation. The FEP material offers excellent dielectric properties and chemical resistance. Its gold-plated brass ClickLoc connectors lock securely into place. This locking mechanism prevents loosening due to vibration. Additionally, the connectors resist corrosion for long-term reliability. The 330730-040-00-CN maintains a typical capacitance of 69.9 pF/m (21.3 pF/ft). This low capacitance preserves signal quality over the full 4.0-meter length.
The country-specific connector option ensures compatibility with local installation practices. Therefore, this cable simplifies procurement for projects with regional requirements. It maintains all the performance characteristics of the standard 3300 XL extension cable. This includes the wide temperature range and robust mechanical design.
The CN option designates a connector configuration tailored for specific countries. This ensures the cable mates properly with local Proximitor Sensor variants or panel interfaces. Bently Nevada offers this option to accommodate different regional standards. Consequently, it eliminates the need for adapters or custom modifications in the field.
This cable includes gold-plated ClickLoc connectors with the country-specific interface. ClickLoc connectors lock positively into place, preventing accidental disconnection. The patented design ensures a reliable electrical and mechanical connection. Furthermore, the gold plating provides excellent conductivity and corrosion resistance.
The 3300 XL 11 mm extension cable with CN option works with all standard 3300 XL probes. The probe comes standard with a locknut featuring pre-drilled safety wire holes. This locknut ensures secure mounting even under severe vibration. All transducer system components share the same high-quality construction. This standardization simplifies installation and maintenance across your monitoring system.
Additionally, connector protectors are available for humid or moist environments. However, silicone tape is also provided with each extension cable. You can use silicone tape as an alternative to connector protectors. But remember, silicone tape is not recommended when the connection will be exposed to turbine oil. For oil-exposed applications, we strongly recommend using the connector protectors instead.
The Bently Nevada 330730-040-00-CN delivers consistent electrical performance over its 4.0-meter length. The DC resistance from center conductor to center conductor (RCORE) is 1.0 ± 0.25 ohms. The resistance from coaxial conductor to coaxial conductor (RJACKET) measures 0.3 ± 0.1 ohms. These values ensure proper impedance matching with the 3300 XL Proximitor Sensor.
For field wiring, this cable accepts conductors from 0.2 to 1.5 mm² (16 to 24 AWG). We recommend using a three-conductor shielded triad cable for optimal noise rejection. The maximum field wiring length between the Proximitor Sensor and the monitor is 305 meters (1,000 feet). However, check the frequency response graph for signal rolloff at extended lengths.
When combined with the 3300 XL probe, the system's linear range spans 4.0 mm (160 mils). The linear range starts at approximately 0.5 mm (20 mils) from the target. It then extends from 0.5 to 4.5 mm (20 to 180 mils), corresponding to -1 to -17 Vdc. The recommended gap setting is 2.5 mm (100 mils) for optimal linearity. The incremental scale factor (ISF) is 3.94 V/mm (100 mV/mil) with ±10% interchangeability error.
This extension cable offers a wide operating temperature range of -51°C to +177°C (-60°F to +351°F). For storage, the range extends slightly to -52°C to +177°C (-62°F to +351°F). Therefore, it performs reliably in extreme industrial environments. The optional flexible AISI 302 SST armor with FEP outer jacket provides extra mechanical protection.
The armored version weighs 140 g/m (1.5 oz/ft), totaling 0.56 kg for the 4.0-meter length. The unarmored version weighs only 45 g/m (0.5 oz/ft), totaling 0.18 kg. Choose the armored option for installations where abrasion or impact is a concern. The probe tip material is polyphenylene sulfide (PPS), which offers excellent wear resistance. The probe case uses AISI 304 stainless steel for corrosion resistance.
Bently Nevada's patented TipLoc molding method ensures a robust bond between the probe tip and body. Meanwhile, the CableLoc design securely attaches the cable to the probe tip. This provides 330 N (75 lb) pull strength for reliable connections. All these features make the 330730-040-00-CN a durable choice for critical machinery protection.
Proper installation ensures accurate measurements and long service life. First, verify that the 4.0-meter length suits your system requirements. This cable works within 5 or 9-meter total system lengths. Next, connect the cable securely to both the probe and the Proximitor Sensor. Ensure the country-specific connectors are fully engaged and locked.
Set the probe gap to the recommended 2.5 mm (100 mils) for optimal performance. Use the ISF of 3.94 V/mm (100 mV/mil) for calibration. Remember that the extended DSL range (0.5 to 5.0 mm / -1 to -19 Vdc) is not applicable with zener barriers. When routing the cable, avoid sharp bends and excessive strain. The tensile strength limits are 330 N for the probe case and 270 N for the connectors.
For installations in humid environments, install the connector protectors for added moisture resistance. For armored cables, ensure the armor does not contact live electrical parts. The country-specific connector design simplifies integration with local equipment. Always follow local electrical codes and safety regulations during installation.

The gross weight for the armored version is approximately 0.56 kg. For the unarmored version, the weight is about 0.18 kg. Please confirm your desired version when ordering. Our team inspects every cable before shipment to guarantee quality.
Q1: What does the CN option mean for this extension cable?
The CN option designates a country-specific connector configuration. This ensures the Bently Nevada 330730-040-00-CN complies with regional electrical and mechanical standards for specific markets.
Q2: Is this cable compatible with standard 3300 XL Proximitor Sensors?
Yes, the 3300 XL 11 mm extension cable with CN option works with all standard 3300 XL Proximitor Sensors. However, verify that the connector matches your specific Proximitor Sensor model.
Q3: Can I use this cable with the FluidLoc option?
No, the FluidLoc option is a separate connector and cable option code (10). The CN option is for country-specific connectors only. Please specify your requirements when ordering.
Q4: What is the difference between the CN and standard connector options?
The standard option (00) uses the default connector configuration. The CN option uses a connector tailored for specific countries to meet regional requirements. Both maintain the same electrical performance.
