FAQ
Q: Can the PR9350/04 sensor operate in temperatures below -20°C?
A: The recommended operating range is -20 to 100°C. Operation outside this range may affect sensor accuracy.
Q: What is the main difference between PR9350/04 and PR9350/06?
A: The PR9350/06 supports a larger displacement range of ±75 mm with slightly higher sensitivity (310 mV/V) and better linearity (2.0%), making it suitable for applications requiring extended measurement travel.
