FAQ
Q: Can the PR6423/000‑011 be used for smaller shafts below 20 mm?
A: This model is optimized for shafts ≥20 mm. Smaller diameters may require alternative sensor variants.
Q: How does PR6423/000‑011 compare to the PR6422 series?
A: The PR6423 series features an 8 mm head with greater measuring range (up to 3 mm) compared to the 5 mm PR6422, making it better suited for larger shaft displacements.
Q: Which converters are recommended for signal conditioning?
A: CON031 converters are commonly paired with this sensor for standardized output and extended range performance.
