Product Introduction
The 330930-040-01-05 is specifically designed to transmit low-level analog signals generated by an eddy current proximity probe.
During operation, the proximity probe detects changes in the distance between its sensing surface and the rotating shaft. These variations are converted into electrical signals that represent shaft vibration and displacement.
The extension cable transfers these signals to the Proximitor sensor while preserving signal quality. Its shielded coaxial construction minimizes external electrical interference and signal loss, ensuring that the monitoring system receives accurate measurement data.
Reliable signal transmission is essential because the accuracy of machinery protection systems depends on the integrity of every component within the measurement chain. The 330930-040-01-05 plays an important role in maintaining stable operation and dependable monitoring performance.

Working Principle
The 330930-040-01-05 functions as a signal transmission component within the proximity transducer system.
The operating process includes the following steps:
- The proximity probe generates an electromagnetic field.
- The rotating shaft influences the electromagnetic field as its position changes.
- The probe converts these changes into proportional electrical signals.
- The extension cable transfers the signals to the Proximitor sensor with minimal interference.
- The monitoring system processes the signals to determine shaft vibration, displacement, position, and other mechanical parameters.
The cable itself does not perform measurement but is essential for preserving signal quality throughout the monitoring system.
