01. Product Engineering Profile
Bently Nevada 330930-065-02-05 is a 3300 NSv Extension Cable. It connects a compatible proximity probe to its Proximitor Sensor. The cable transfers displacement signals within industrial machinery monitoring systems.
This configuration provides a 6.5-meter cable length and stainless steel armor. Its armor does not include an FEP outer jacket. The 75-ohm coaxial construction uses FEP electrical insulation.
The cable supports proximity measurement installations that require mechanical protection. Its electrical characteristics match the specified 3300 NSv measurement system requirements. Engineers must verify the complete probe and sensor configuration before installation.

Measurement Principle: The compatible 3300 NSv proximity system uses eddy-current sensing. The probe detects target displacement without mechanical contact.
Engineering Clarification: Measurement range and output voltage describe the complete proximity measurement system. They are not independent extension cable specifications.
The supplied data does not specify numerical sensitivity, resolution, or frequency bandwidth. Engineers should consult the complete system documentation for these parameters.
05. Mechanical Construction and Protection
The model combines electrical insulation with flexible stainless steel armor. Its configuration excludes the FEP outer jacket around the armor.
| Mechanical Feature | Specification |
|---|---|
| Armor Material | Flexible AISI 302 stainless steel |
| Armor Protection | Stainless steel armor without FEP outer jacket |
| Coaxial Insulation | FEP |
| Connector Construction | Gold-plated brass |
| Probe Case to Probe Lead | 220 N (50 lb) maximum rated tensile strength |
| Probe Lead to Extension Connector | 220 N (50 lb) maximum rated tensile strength |
| Probe Case to Stainless Steel Armor | 220 N (50 lb) maximum rated tensile strength |
The stainless steel armor provides mechanical reinforcement. Installers should still prevent crushing, sharp bending, and excessive pulling force.
06. Operating Environment and Temperature Limits
| Environmental Parameter | Specification |
|---|---|
| Operating Temperature | -52°C to +177°C |
| Storage Temperature | -52°C to +177°C |
| Fahrenheit Range | -62°F to +351°F |
| Armor Configuration | Stainless steel without FEP outer jacket |
The cable supports installations with wide temperature variations. Confirm the connector and probe temperature limits separately.
Environmental Selection Advice: The unjacketed armor configuration does not provide the same outer environmental barrier as FEP-jacketed armor. Consider moisture, chemical exposure, and installation contact conditions.
07. System Length and Field Wiring Requirements
The extension cable must match the complete 3300 NSv measurement system configuration.
Total Length Rule:
Probe Length + Extension Cable Length = Required Proximitor Sensor Total Length.
For this model, the extension cable contributes 6.5 meters. Confirm the compatible probe length before connecting the system.
| Field Wiring Parameter | Specification |
|---|---|
| Wire Cross-Section | 0.2–1.5 mm² |
| AWG Range | 16–24 AWG |
| Wiring with Ferrules | 0.25–0.75 mm² |
| AWG with Ferrules | 18–23 AWG |
| Recommended Wiring | Three-conductor shielded triad cable |
| Maximum Field Wiring Length | 305 m (1,000 ft) |
The field wiring connects the 3300 XL NSv Proximitor Sensor to the monitor. Longer wiring can reduce high-frequency signal response.
08. Installation and Commissioning Workflow
Stage A – Pre-installation Verification

10. Diagnostic Applications and Troubleshooting
This extension cable does not contain independent diagnostic electronics. Technicians can assess its condition through electrical testing and monitoring system observations.
| Diagnostic Symptom | Potential Cause | Recommended Inspection |
|---|---|---|
| Unstable displacement readings | Loose connector or cable damage | Inspect connector engagement and cable continuity |
| Unexpected gap voltage | Incorrect probe gap or system mismatch | Check probe positioning and sensor configuration |

Alternative Product: Bently Nevada 330930-065-04-00
Engineering Selection Recommendations
- Choose 330930-065-02-05 when the required length is 6.5 meters and the installation specifies unjacketed stainless steel armor.
- Consider 330930-065-04-00 when its verified connector and armor configuration matches the existing installation.
- Compare the complete suffix codes before replacing an installed cable.
- Check the required agency approvals for the installation location.
- Verify the probe and Proximitor Sensor total system length.
Important: Both models share the 6.5-meter length designation. Their remaining configuration details require manufacturer documentation. Do not assume direct interchangeability based on length alone.
12. Certification and Compliance Information
The final suffix 05 identifies the Multiple Approvals option.
The supplied product information does not list individual certificate numbers. Confirm the exact approval documents and installation conditions before using the cable in regulated hazardous areas.

14. Global PLC Spare HUB's Insight
The 330930-065-02-05 offers a specific mechanical protection configuration for the 3300 NSv proximity measurement system.
Its defining feature is the stainless steel armor without an FEP outer jacket. This distinction matters when engineers compare cable routing, environmental exposure, and mechanical protection requirements.
Three considerations deserve particular attention during procurement:
- Electrical Integrity: Confirm 75 Ω impedance and the specified capacitance characteristics.
- Mechanical Configuration: Verify the armor construction and outer jacket requirement.
- System Calibration: Match the probe and extension cable lengths to the Proximitor Sensor configuration.
In field maintenance, connector contamination and cable damage can create intermittent measurement problems. A structured inspection should include connector contacts, conductor continuity, armor condition, and sensor output.
Our technical recommendation is to verify the entire measurement chain before replacement. This practice helps prevent incorrect cable selection and unnecessary commissioning work.
15. Frequently Asked Questions
1. Does the unjacketed stainless steel armor affect cable installation?
Yes. The exposed armor requires careful routing around sharp edges and abrasive surfaces. Consider additional environmental protection when the installation involves moisture or chemical exposure.
2. Can technicians shorten the 6.5-meter extension cable during installation?
Do not modify the cable length without manufacturer approval. Cable modification can change electrical characteristics and system calibration. Select the correct factory configuration instead.
3. What inspection method helps identify early cable deterioration?
Combine visual inspection with electrical continuity and resistance measurements. Pay particular attention to connector interfaces and areas with repeated vibration. Compare results against commissioning records.
4. Why can a proximity monitoring channel show unstable readings after cable replacement?
Incorrect total system length can affect the electrical response. Connector mismatch, damaged conductors, or incorrect probe positioning can also cause problems. Verify the complete assembly before adjusting monitoring thresholds.
5. What information should procurement teams provide when requesting a replacement cable?
Provide the complete part number, installed probe model, Proximitor Sensor model, required cable length, and environmental conditions. Include the approval requirements and armor preference. These details help prevent configuration errors.
