Product Q&A
- Q: What does the “CN” suffix indicate in this part number?
- A: The “CN” typically refers to the configuration for specific cable terminations or localized compliance standards for the Chinese industrial market.
- Q: Does this sensor require a driver to function?
- A: Yes, the PR6423 must be used with a compatible CON series signal converter (driver) to output a voltage signal.
- Q: Can this sensor operate in oil-submerged environments?
- A: Yes, the sensor tip is pressure-resistant and designed to operate reliably in oil-mist or oil-submerged conditions.
