The FD-G500 is a digital fiber sensor component designed for the FX-300 series photoelectric sensing system. While the SPEC_CONTEXT contains multiple fiber types and accessories referenced in tables and product listings, the specific technical parameters directly attributable to the FD-G500 designation are not explicitly isolated in the provided documentation. The datasheet describes various fiber sensor configurations, sensing ranges, and optional accessories for the FX-300 series platform, but does not clearly delineate which specifications apply uniquely to the FD-G500 model. The FX-300 series emphasizes stable sensing performance, high-speed response capabilities (35 µs ultra high-speed response available), and programmable settings via four-digit code input for response time, hysteresis, display mode, and timer functions. Applications include LCD and semiconductor industry detection tasks, with support for specialized sensing scenarios such as glass substrate detection, liquid level sensing, and high-temperature environments.
