The Wenglor RO88PD3 is a compact retro-reflective sensor that requires a reflector for operation. Featuring a red light source and polarization filter, it reliably detects objects—both glossy and matte. With a range up to 2,500 mm and a fast 1 ms response time, it is ideal for automation processes like assembly lines, conveyors, and packaging. The sensor’s IP65 protection rating and fully encapsulated housing ensure industrial durability.
