Description
Overview
The PR6424/006‑131 (CON041) is an 8 mm eddy‑current proximity sensor from Emerson’s EPRO series, designed for non‑contact measurement of shaft displacement, vibration, and position on rotating machinery. It forms part of a complete proximity measurement chain when paired with compatible extension cables and signal converters.
Functional Characteristics
This sensor operates using eddy‑current technology to detect minute changes in the distance between the probe tip and a conductive target surface. Its design ensures stable linearity, low noise, and high repeatability, making it suitable for condition monitoring and machinery protection systems. The 8 mm tip diameter provides a balanced combination of measurement range and sensitivity.

FAQ
Q: What is the measurement range of the 8 mm probe A: Typical PR6424 8 mm probes support a nominal range of approximately 2–3 mm, depending on the converter used.
Q: Can this sensor be used with non‑Emerson monitoring systems A: Yes. When paired with the appropriate converter, it provides standard conditioned outputs compatible with many third‑party systems.
Q: Does the sensor include the converter module A: No. The CON041 converter must be ordered separately.
