SUNX FX-75 Fiber Optic Sensor

The SUNX FX-75 Fiber Optic Sensor is a General Purpose fiber sensor in the FX4N family from SUNX (Panasonic Industrial Devices SUNX). In older SUNX catalogs it is listed as a General Purpose Fiber Sensor within the FX4N Series (FX4N-A3R-OFD), reflecting its role as part of SUNX’s modular, fiber-based sensing lineage. The model is documented as discontinued in June 2001, marking it as a legacy part within SUNX’s historical product lineup. Historically these FX4N-based sensors were designed to be paired with a compatible fiber head and FX4N interface to deliver straightforward fiber-optic sensing in automation and manufacturing environments. While modern SUNX offerings in the FX family have evolved with newer digital functionality and IO‑Link compatibility, the FX-75 remains a reference point in the company’s long history of general‑purpose fiber sensing solutions.
