Product Introduction
BENTLY 330930-045-00-CN is a 4.5-meter extension cable for 3300 XL NSv systems. It bridges the probe and proximitors without degrading the high-frequency eddy current signal.
This industrial automation unit uses low-capacitance FEP construction to maintain linearity. The “-CN” suffix confirms ATEX/IECEx certification for hazardous chemical environments.

Quality Control Process
We validate every BENTLY 330930-045-00-CN before shipment. First, we measure total loop resistance and capacitance with a precision LCR meter. Values must match the 4.5m electrical length within ±2%.
Next, we perform a Time Domain Reflectometry (TDR) sweep to detect internal impedance mismatches or connector crimp failures. Any reflection over -40dB fails the test.
Finally, we inspect the micro-coax pins under magnification and seal each replacement module in anti-static shielding with desiccant. This prevents moisture damage during transit.
Replacement Pitfall Guide
❗ Electrical Length Mismatch: The “045” in your part number means exactly 4.5m. You cannot substitute a 4.0m or 5.0m cable. The total system length (probe + extension) is factory-calibrated; even 10cm of error destroys linearity and sensitivity.
❗ Connector Torque: Hand-tighten the micro-coax connectors, then use a calibrated torque wrench to spec. Over-torquing crushes the center pin; under-torquing causes intermittent signal loss that mimics bearing wear.
❗ Bend Radius Violation: Never bend this cable tighter than 1 inch (25mm) radius. Sharp bends change the characteristic impedance and create signal reflections that the proximitors cannot compensate for.
❗ Hazardous Area Compliance: The “-CN” suffix denotes specific ATEX/IECEx certification. Do not substitute a non-CN part in classified zones, as it violates safety compliance.
Keep these in mind and you’ll cut 90% of rework time.
