CGF photoelectric sensors offer diffuse, retro-reflective and through-beam arrangements in 30, 50 and 70 housing groups. The DC transistor selection uses NPN or PNP outputs, while the relay selection provides NO+NC contacts. Choose the optical arrangement and range, then the output circuit, supply and mounting format. Product images illustrate housing and sensing arrangements; use the model tables for electrical selection.
