Technical Specifications

Function and Working Principle

The 330780-51-CN sensor utilizes eddy current proximity sensing technology to measure the distance between the sensor probe and a conductive surface.

Working principle:

• The probe generates a high-frequency electromagnetic field
• When a conductive surface approaches, eddy currents are induced
• Variations in the electromagnetic field are converted into an electrical signal
• The output signal corresponds to vibration or displacement

This non-contact measurement method enables precise, real-time monitoring without physical wear, ensuring long-term reliability.
