Technical Specifications

Function and Working Principle

The 330780-51-00 sensor uses eddy current proximity sensing technology to measure the distance between the sensor probe and a conductive target surface.

Working process:

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

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