The FZAM18P1155 is a diffuse photoelectric sensor that operates using an intensity difference principle. It features a sensing distance of 20 to 150 mm, which can be extended to 30 to 280 mm with a doubling lense, and utilizes a pulsed infrared diode light source at an 880 nm wavelength. This sensor provides a fast response time of less than 0.5 ms, a PNP light operate output, and operates on a supply voltage of 10 to 30 VDC. Housed in a robust, IP65-rated brass nickel-plated M18 threaded body, it is well-suited for industrial automation applications requiring reliable object detection in various ambient conditions.
