Industrial Proximity Probe Extension Cable Assembly
Model: 330851-02-000-050-10-00-CN
1. Brand & Product Positioning
The product belongs to a high-precision industrial vibration monitoring ecosystem used for rotating machinery protection. It is part of a widely adopted proximity measurement architecture designed for shaft displacement, vibration monitoring, and condition-based maintenance.
The overall system is commonly associated with a global industrial instrumentation brand specializing in machinery health monitoring and predictive diagnostics.
This model is a China-specific configuration version (suffix “CN”), typically indicating regional packaging, labeling, or supply specification differences while maintaining the same core electrical and mechanical performance standard.
2. Product Overview
This model is a proximity probe extension cable assembly used to connect a proximity sensor (probe) to a signal conditioning or monitoring module.
Its function is to ensure stable transmission of high-frequency eddy current signals generated by the probe when measuring shaft vibration and position.
The cable is factory-terminated, meaning both ends are pre-fitted with precision connectors to guarantee consistent signal integrity and reduce installation variability.
It is engineered for continuous operation in heavy industrial environments where machinery operates under high temperature, vibration, oil exposure, and electromagnetic interference.
