Panasonic FX-500 is a highly advanced digital fiber sensor with high end features and a class leading stability and performance. An exclusive detection ASIC, designed specifically for the FX-500, is capable of processing ultra high-speed calculations while offering a long sensing range. Due to the impressive capabilities of this sensor, high precision detections can now be carried out where they were previously not possible. A highly visibility dual digital display allows for simultaneous viewing of the threshold and incident light values for quick and effective setup and usage. The display is large, bright, and has a wide viewing angle for easily reading values from a distance. Teaching the amplifier is now done through the RUN mode of the amplifier, simplifying the setup process down to two presses of the 'set' button. The user can also directly change the threshold value using the '+' and '-' buttons.
