Overview
The Epro PR6423/014-010 CON021 is an 8 mm eddy current sensor designed for non-contact displacement measurement. It measures the position of a ferromagnetic target without physical contact, making it suitable for shaft displacement and proximity monitoring. The sensor provides a 2 mm linear measurement range and uses a defined initial air gap and incremental scale factor for measurement setup and calibration.
Product Features
- Non-contact measurement: Uses eddy current technology to measure the distance between the sensor tip and a conductive target without physical contact.
- 8 mm sensor design: Supports displacement measurement with a 2 mm linear range.
- Defined measurement characteristics: Provides an initial air gap of 0.5 mm and an incremental scale factor of 8 V/mm.
- Specified target material: Uses 42CrMo4 (AISI/SAE 4140) ferromagnetic steel as the standard target material. Other materials are available on request.

Measurement Characteristics
The PR6423/014-010 uses eddy current technology to detect changes in the distance between the sensor and a conductive target. The measurement principle does not require direct contact, allowing the sensor to monitor relative displacement while the target is moving.
Furthermore, the 8 V/mm incremental scale factor defines the relationship between displacement and output signal change. Its specified tolerance is +/- 5% within the temperature range of 0 to 45 deg C. The deviation from the best fit straight line is +/- 0.025 mm over the same temperature range.
Target Material and Installation Conditions
The specified standard target material is 42CrMo4 (AISI/SAE 4140) ferromagnetic steel. Target material affects eddy current measurement characteristics, so the specified material should be considered when checking measurement accuracy and sensor configuration.
In addition, the minimum shaft diameter is 25 mm. The initial air gap of 0.5 mm is a defined measurement parameter and should be considered when establishing the sensor position.
