IT23S is Banner Engineering’s inline glass-fiber optic assembly designed for high-temperature sensing environments. It uses a 0.914 m (3 ft) glass fiber in a round, stainless steel monocoil jacket with a brass sensing end, and a 3 mm (0.12 in) fiber diameter. The end connects via a #5/16‑24 thread, and the sensing end segment is threaded, with the assembly being non-retractable. This IT23S fiber assembly is intended for use with Banner’s fiber optic sensing systems to deliver light through the fiber path in compact installations.
