Industrial photoelectric sensors are widely used in industrial environments to determine the distance and presence of objects by transmitting light of a specific wavelength. They detect changes in the transmitted light returned to the receiver to achieve the goal of ignoring ambient light. The sensor is designed with a very sturdy structure to withstand the harsh conditions of the industrial environment. The sensor's grabbing methods include crossed beam, retro-reflective, diffuse, reflection, backscatter, transmission, proximity, distance, and line focus. These sensors can be used more effectively by distinguishing factors such as light source color and wavelength, sensing distance, intrusion protection, and output configuration.
