[OMRON] — E3C-LDA Laser Photoelectric Sensor Head (Diffuse / Retro-reflective, Spot/Line/Area)
Family ID: OMRON-E3C-LD-HEAD
OMRON E3C-LDA series laser photoelectric sensor heads with separate digital amplifier. Variable laser beam — spot, line, or area detection. E3C-LD11N 2M: diffuse-reflective, variable spot, sensing distance 1 m, Class 2. E3C-LR11N 2M: coaxial retro-reflective with MSR function, variable spot, 7 m, Class 2 (requires reflector E39-R12/R13/R14/RS4/RS5, sold separately). E3C-LR12N 2M: coaxial retro-reflective with MSR function, 2.0 mm fixed spot, 7 m, Class 1. Beam Units (E39-P11/P21 for LD11N, E39-P31/P41 for LR11N) for line/area beam sold separately. Compatible amplifier: E3C-LDA series only. Cable length: 2 m.
