The FX-300 series of digital fiber optic sensors offers a wide range of sensing possibilities in a compact, high-performance unit. The FX-300 series was designed around ease of use. The incorporation of a user-friendly jog-dial simplifies operation and maintenance. Beginners and advanced users alike will benefit from the intuitive programming and operation, thus, keeping the learning curve to a minimum. The optical communication function makes it easy to copy settings to up to 16 sensors connected together. This saves the time of setting up each sensor individually. Restoring settings has never been easier than with the quick set-up code that is built into the FX-300 series. Once initial set-up is completed, write down the four digit code and in the event that sensor settings are reset, the user can quickly restore the sensor back to operation.
