The Omron E32-DC200F is a fiber optic cable with a polyethylene (PE) sheath and a PMMA (acrylic) core, designed for use with Omron fiber amplifiers in sensing applications where the amplifier body is remote from the sensing point. The 1.8 cm minimum bend radius is the key mechanical constraint — tighter bends will attenuate the signal or damage the fiber. That 18 mm radius is tighter than many jacketed plastic fibers, which means it can snake through tighter cable ducts or around panel edges without losing light.
Signal integrity and installation notes
The PE sheath gives this cable better chemical resistance than PVC-jacketed fibers — important if the cable passes through washdown zones or sees occasional oil mist. The PMMA core is standard for visible-red fiber amplifiers; it transmits 660 nm light efficiently but has higher attenuation than glass fiber at longer runs. Keep the cable length under 2 m for reliable triggering with standard Omron E3X amplifiers. The 1.8 cm bend radius is the minimum, not the recommended. For long-term reliability, design the cable path with at least 2.5 cm radius. A kink at the amplifier connector is the most common field failure on these fibers — the PE jacket hides the internal crack until the signal drops out intermittently.
