Product Introduction
The Epro PR6423/00R-031 is a high-performance 8mm eddy current sensor designed for non-contact measurement of dynamic displacement, position, eccentricity, and speed in critical turbomachinery applications. It is part of Emerson’s AMS product line, renowned for precision and reliability in harsh industrial environments.
This sensor features a reverse mount configuration (R) with a M10x1 thread, standard non-armored cable, and a Lemo connector. It is ideal for applications requiring robust performance in high-temperature, high-vibration, or hazardous areas.

FAQ
Frequently Asked Questions (FAQ)
Q1: What is the difference between PR6423/00R-031 and PR6423/000-000?
A1: The “R” denotes a reverse mount configuration, while the standard model has a forward mount. The “031” indicates a 5.0m cable length.
Q2: Can this sensor measure non-ferrous metals?
A2: No, it is optimized for ferromagnetic steels like AISI 4140. For non-ferrous targets, consult Emerson for alternatives.
Q3: Is the cable length customizable?
A3: Yes, cable lengths from 4.0m to 10.0m are available (e.g., “031” = 5.0m).
Q4: What is the lifespan under radiation exposure?
A4: The RAD variant lasts ~18 years under neutron radiation (0.5Sv/h). Standard models are not radiation-rated.
Q5: How do I interpret the model number?
A5: Example: PR6423/00R-031 = 8mm sensor, M10x1 thread, reverse mount, 5.0m cable, Lemo connector.
Q6: Can the sensor withstand oil or coolant exposure?
A6: Yes, the IP66 rating protects against oils and coolants, but prolonged immersion is not recommended.
Q7: What is the recommended air gap during installation?
A7: 0.5 mm (20 mils) initial gap, adjustable within the 2 mm linear range.
Q8: Are replacement cables available?
A8: Consult Us.
