The E3FC-DN25 is a digital diffused reflective photoelectric sensor manufactured by Omron. It is a high-precision sensor that uses a background suppression function to reduce the impact of ambient light conditions on sensing performance. It is designed to accurately detect targets in a variety of materials, including metal, paper, wood, plastic and glass. The E3FC-DN25 has a sensing distance of up to 100mm plus an adjustable sensing window to make sensing more precise. The sensor is also equipped with a self-diagnosis function and LED indicator to quickly identify problems. It is dust-proof and waterproof, making it suitable for use in many difficult environments.
