Our photoelectric sensors provide non-contact, accurate detection of targets. They emit infrared, red or laser light and switch to an output state if a target interrupts the emitted light. These units come in three primary types: through-beam, retro-reflective and diffuse. These sensors can check for presence, color, distance, size, shape, and many more applications. They perform at longer distances than alternative sensing methods, while offering many mounting options and the ultimate in flexibility.
