330130-045-02-05 is a Bently Nevada 3300 XL series standard extension cable with a total length of 4.5 meters (14.8 feet). This model features standard FEP-insulated cable and includes pre-installed connector protectors that provide environmental sealing, while carrying CSA, ATEX, and IECEx hazardous area approvals for safe use in intrinsically safe (IS) installations in explosive atmospheres.
It is an essential component of the 3300 XL 8 mm eddy current probe system, specifically designed for applications requiring the precise 4.5 meter length to match a 0.5 meter hazardous area approved probe to form a complete 5 meter intrinsically safe system, along with environmental sealing for connectors without the need for mechanical armor. Typical applications include vibration monitoring of compressors, pumps, and turbomachinery in Zone 0 and Zone 1 hazardous areas such as refineries, petrochemical plants, and natural gas facilities, where oil mist, moisture, or conduit routing is present. When using a 0.5 meter hazardous area approved probe (e.g., 330101-XX-05-XX-05), a 4.5 meter hazardous area approved extension cable is required to form a complete 5 m IS system (0.5 m + 4.5 m = 5 m). This model is specifically designed for such precise total length matching in hazardous area applications while providing connector environmental sealing.
Model Breakdown: 330130-045-02-05 Configuration Details

Key Configuration Note: The combination of 045, 02, and 05 is the defining feature of this model. In a 3300 XL intrinsically safe system, when using a 0.5 meter hazardous area approved probe (e.g., 330101-XX-05-XX-05), a 4.5 meter hazardous area approved extension cable is required to form a complete 5 m IS system (0.5 m + 4.5 m = 5 m). This model meets this precise total length matching requirement while providing pre-installed connector protectors that offer oil sealing, dust protection, and moisture resistance for hazardous area applications, and without armor for applications with minimal mechanical stress.
Connector Protector Details
What is a Connector Protector?
The connector protector is a fluorosilicone sealing sleeve pre-installed on the cable connector end. After connector mating, it forms a sealing barrier that protects the connector interface from environmental damage.
Functions of the Connector Protector
Environmental Sealing: Prevents turbine oil, moisture, and dust from penetrating the connector interface, reducing the risk of signal degradation or short circuits
Enhanced Connection Reliability: Forms a sealed sleeve after connector mating, ensuring long-term connection stability
Media Ingress Prevention: In oil mist environments, the protector prevents oil from seeping through the connector threads
Intrinsic Safety Integrity: In hazardous areas, connector protectors help maintain sealing at the connection point, preventing media ingress that could affect intrinsic safety performance
Easy Installation: Pre-installed; users only need to tighten the ClickLoc connector normally — no special tools required
Important Note: The datasheet specifically notes that silicone tape is not recommended for applications where the probe-to-extension cable connection will be exposed to turbine oil, and connector protectors are the recommended alternative. This model, with pre-installed connector protectors and hazardous area approvals, is the ideal choice for oil mist or moisture-prone environments in hazardous areas.

Conditions of Safe Use (Intrinsically Safe Systems)
When used in an intrinsically safe system, the following conditions must be observed:
Barriers/Isolators: Must be installed with intrinsically safe zener barriers per Bently Nevada drawing 141092, or with galvanic isolators.
Entity Parameters (when connected to approved Proximitor Sensor):
Ui = -28V
Ii = 140 mA
Pi = 0.91 W
Ci = 47 nF
Li = 1460 μH
Installation Environment: The Proximitor Sensor must be installed in a non-hazardous area or within an approved explosion-proof enclosure.
Important: This cable must be used with hazardous area approved probes (e.g., 330101-XX-05-XX-05) and Proximitor Sensors (e.g., 330180-50-05) to maintain a complete intrinsically safe system. Mixing with non-approved components will void the hazardous area certification.
Application Scenarios & Selection Guide
330130-045-02-05 is suitable for the following typical applications:
Precise Total Length Matching for 5 m IS Systems (0.5 m Hazardous Area Probe) + Connector Environmental Sealing: When using a 0.5 meter hazardous area approved probe, a 4.5 meter hazardous area approved extension cable is required to form a complete 5 m IS system (0.5 m + 4.5 m = 5 m). This model meets this precise total length matching requirement while providing connector environmental sealing, making it ideal for hazardous area environments with oil mist, moisture, or conduit routing.
Hazardous Area Environments with Oil Mist or Moisture: Near compressors, pumps, and gearboxes in refineries and chemical plants, oil mist or moisture may be present. Connector protectors effectively prevent media ingress, while hazardous area approvals ensure safety compliance.
Conduit Routing in Hazardous Areas (Requiring Connector Protection): When cables must be routed through metal conduit and the connector may contact the conduit wall or experience friction, protectors provide additional protection, while hazardous area approvals maintain system integrity.
Cost-Sensitive Hazardous Area Environmental Sealing Requirements: Compared to the 03-05 option (armored + protector + approvals), this model provides protectors without armor, reducing procurement cost while still meeting environmental sealing and hazardous area requirements — ideal for hazardous area applications with minimal mechanical stress.
Selection Notes:
Total Length Matching: Probe length + extension cable length = Proximitor Sensor total system length (5 m or 9 m). Verify your probe length: if using a 0.5 m hazardous area approved probe, select this model (4.5 m); if using a 1.0 m hazardous area approved probe, select a 4.0 m extension cable with protector and hazardous area approvals (e.g., 330130-040-02-05).
System Integrity: All components entering the hazardous area (probe, extension cable, connector protectors) must carry the same hazardous area approval rating. This model includes pre-installed protectors that meet hazardous area sealing requirements.
Connector Protector Maintenance: Protectors are pre-installed and require no field assembly. If removal for inspection is necessary, ensure proper reinstallation to maintain seal integrity and intrinsic safety system requirements.
Ambient Temperature: If the application environment exceeds +177°C, consider the ETR (Extended Temperature Range) cable with protector and hazardous area approvals series (e.g., 330190-045-02-05).
Armor Requirements: If the installation environment also involves mechanical impact, crushing, or abrasion risks, consider the armored + protector + hazardous area approvals version (e.g., 330130-045-03-05).
Comparison with Common Lengths
Model | Length | Protector | Armor | Approvals | Typical Matching Probe | System |
330130-040-02-05 | 4.0 m | Yes | No | ATEX/IECEx | 1.0 m hazardous area probe | 5 m IS system |
330130-045-02-05 | 4.5 m | Yes | No | ATEX/IECEx | 0.5 m hazardous area probe | 5 m IS system |
330130-080-02-05 | 8.0 m | Yes | No | ATEX/IECEx | 1.0 m hazardous area probe | 9 m IS system |
330130-085-02-05 | 8.5 m | Yes | No | ATEX/IECEx | 0.5 m hazardous area probe | 9 m IS system |
Standard 5 m intrinsically safe systems are typically composed of a 1.0 m hazardous area probe + 4.0 m hazardous area cable, or a 0.5 m hazardous area probe + 4.5 m hazardous area cable. Choose the extension cable length that matches your probe. This model provides a connector environmental sealing option for 5 m IS systems using a 0.5 m hazardous area probe.
Mechanical Dimensions & Installation
Cable Outer Diameter: Standard cable 3.68 mm (0.145 in) maximum
Connector Protector Outer Diameter: 12.4 mm (0.49 in) maximum
Connector: Features the ClickLoc design. Finger-tighten until an audible "click" is heard — no special tools are required. The protector automatically forms a seal when tightened.
Installation Drawing: Intrinsically safe system installation must strictly follow Bently Nevada drawing 141092, including barrier selection, grounding, and wiring practices.
Installation Tips: When routing through conduit in hazardous areas, use a pull rope or fish tape attached to the cable jacket (not the connector protector) to avoid stress. If protector removal is required for inspection, refer to the datasheet for tool instructions, and ensure proper reinstallation to maintain seal integrity.
