How It Works

The EPRO PR6423/128-110 uses eddy current technology to measure the proximity of metallic objects. The sensor forms an oscillator circuit with a signal converter (CON). The amplitude of the oscillation is dampened when a metallic object approaches the sensor. This damping is directly proportional to the distance between the sensor face and the object, providing precise displacement measurements.

The system arrives fully adjusted, so there is no need for complex on-site calibration. The user simply adjusts the gap between the sensor and the object to achieve the specified signal output, ensuring ease of use and quick setup.

Key Features

• Contactless Measurement: Reduces wear and tear, ensuring longer sensor life and minimal maintenance.
• High Sensitivity: Provides accurate measurements with a sensitivity of 8 V/mm (203.2 mV/mil).
• Rugged Design: Built to withstand harsh environments, ensuring reliable performance in industrial settings.
• Pre-Calibrated System: Delivered fully adjusted for immediate operation.
• Wide Operating Temperature Range: Operates between -35°C to +180°C (-31°F to +356°F), suitable for a variety of applications.
