M18 DC Photoelectric Switches FA are compact M18 barrel type photoelectric switches for DC operation. This series includes M18 photoelectric sensors, 10-30VDC, models with axial and 90 degree optics, models with IR, red light and red light laser emission, red light emission for transparent object detection, metal and plastic housings, models with or without sensitivity adjustment, IP67 protection and UL and CUL approved.
This manual covers the IMO M18 series of DC photoelectric switches, describing the various emitter and receiver options, optics configurations, and ordering codes. It includes detailed specifications such as operating voltage, load current, protection ratings, and environmental limits.
The document also provides mechanical dimensions, characteristic curves, and wiring connection diagrams for both axial and right‑angle cable exits, helping users install and configure the switches for diffuse, retro‑reflective, and laser applications.
