Photoelectric sensors use a beam of light to detect the presence or absence of an object. This technology is used for applications where long sensing distances are required and proximity sensors do not provide an effective solution. The Allen-Bradley range of photoelectric sensors satisfy applications found in many industries, such as material handling, packaging, food processing, and transportation.
