Banner Engineering Photoelectric Sensors are designed to detect the presence, absence or surface condition of objects in industrial automation applications using a light beam. When the emitted light is interrupted or reflected by a target, the receiver detects the change and generates an output signal. The product family includes opposed, retroreflective, polarized retroreflective, diffuse, background suppression and laser-based sensing technologies. Plastic and metal housings, compact and cylindrical designs, IO-Link models and multiple IP protection ratings make the range suitable for packaging, logistics, food and beverage, pharmaceutical, material handling and general machine automation applications.
