Product Series
3300 XL Series
The 330930-040-01-00 belongs to the 3300 XL Series, one of the most recognized machinery protection product families for rotating equipment monitoring.
The series is designed to provide continuous measurement of shaft vibration, shaft position, eccentricity, thrust position, and rotational movement. Products within this series are widely used in predictive maintenance systems because they deliver stable measurement performance under continuous industrial operation.
The 3300 XL Series consists of proximity probes, extension cables, Proximitor sensors, mounting accessories, and related components that work together as a complete vibration monitoring solution.
Major characteristics of the series include:
- High measurement accuracy
- Excellent electrical stability
- Strong resistance to industrial interference
- Long operating service life
- High compatibility between components
- Reliable performance in continuous-duty environments
- Flexible installation configurations
- Stable signal transmission over extended cable lengths
Product Introduction
The 330930-040-01-00 functions as the communication link between the proximity probe and the signal conditioning unit.
During machinery operation, the proximity probe detects changes in the distance between the probe tip and the rotating shaft. These mechanical movements are converted into electrical signals using eddy current technology.
The extension cable transfers these low-level electrical signals with minimal attenuation, allowing the monitoring system to calculate shaft vibration, shaft position, rotor movement, and mechanical displacement accurately.
A high-quality extension cable is essential because poor signal transmission may reduce measurement accuracy or introduce electrical noise into the monitoring system.
The 330930-040-01-00 is designed to minimize these risks through optimized shielding, durable insulation, and reliable connector construction.

Product Features
Stable Signal Transmission
The extension cable is engineered to preserve sensor signal quality throughout the transmission path, ensuring that monitoring systems receive accurate vibration and displacement information.
Excellent Electromagnetic Protection
Multiple shielding layers reduce the influence of electromagnetic interference commonly found around industrial motors, generators, switchgear, and high-voltage equipment.
Reliable Mechanical Construction
Industrial-grade insulation materials protect the cable from mechanical wear, oil contamination, humidity, and continuous vibration.
High Compatibility
Designed specifically for the 3300 XL proximity measurement system, the cable can be integrated directly with compatible probes and Proximitor sensors without additional modifications.
Long Operating Life
The cable is intended for continuous-duty operation in machinery protection systems where long service intervals and dependable performance are required.
Easy Installation
The standardized cable construction simplifies routing, replacement, and maintenance while supporting various industrial installation layouts.
Working Principle
The extension cable itself does not generate measurement signals.
Instead, it transfers electrical signals generated by the proximity probe.
The working process is summarized below:
- The proximity probe generates an electromagnetic field.
- The rotating shaft changes the electromagnetic field.
- The probe converts the distance variation into an electrical signal.
- The extension cable transmits the signal to the Proximitor sensor.
- The monitoring system processes the signal into vibration or displacement measurements.
Maintaining signal quality throughout this transmission path is essential for accurate machinery protection.
