Photoelectric sensing uses a beam of light to detect the presence or absence of an object. This technology is an ideal alternative to inductive proximity sensors when the required sensing distances are longer or when the item to be sensed is non-metal.
Allen-Bradley photoelectric sensors are recognized as the most robust in the industrial automation marketplace. Designed for reliable operation, our leading products boast feature sets aimed to satisfy mainstream applications found in many industries such as material handling, packaging, food processing, transportation… the list goes on and on. Careful selection of the right features during the design cycle allows us to offer sensors that meet your application needs while remaining simple and easy to apply. For more specialized applications requiring a non-standard connector or cable, customization of sensor connections is also available. No matter how demanding your application, there’s an Allen-Bradley photoelectric sensor option to satisfy your needs... and your budget.
