[OMRON] — E32 LENS in Nut Type Fiber Unit (15° GIGA Beam, Through-beam / Reflective / Retro-reflective)
Family ID: OMRON-E32-LENSIN-NUT
OMRON E32 LENS in Nut Type Fiber Unit — Build-in lens + Nut-type mounting in a single product. 15° narrow aperture angle (GIGA Beam) with high power output for stable detection: approx. 10× light intensity vs non-lens through-beam (E32-LT11N) and approx. 3× S/N ratio vs non-lens reflective (E32-LD11N). Reduces false detection from light reflection in narrow spaces. Patented tool-fit nut structure — spanner inserts deep into nut without contacting fiber cable, preventing fiber damage during installation. Single-nut tightening simplifies mounting. No lens attachment work, no torque management, no risk of lost lens. Includes E39-RP1 Reflector for E32-LR11NP transparent-object detection (required pair). Compatible with E3NX-FA and E3X-HD smart fiber amplifiers. IP50, −40 to +70 °C, bend-resistant R2 cable. Patent registered.
