The E32-D61 2M with Sensor manufactured by Omron is a fiber-optic, diffuse-reflective sensor with a sensing range of up to 270mm. It has a NPN output and can detect transparent, diffuse, and dark materials. It is designed for long-range detection and its wide range allows it to detect objects at a greater distance than conventional sensors. The self-diagnosis functions, including check-mode and sun-check, help reduce setup and maintenance. The standard operating temperature range is -25°C to 70°C. It is RoHS compliant and has UL, CE, and KCC safety certifications.
