This technology helps to eliminate false readings that can occur from reflective surfaces, by ensuring only light reflected directly from a compatible reflector is registered.What are the benefits of two complementary LO/DO outputs?Two complementary LO/DO (Light On/Dark On) outputs provide enhanced flexibility in your automation control. This allows you to configure the sensor to switch based on either the presence or absence of light, offering more adaptable solutions for different application requirements.Is this sensor suitable for outdoor use?While the sensor is robust, its primary design and specifications are optimized for industrial indoor environments. For specific outdoor applications, further assessment of environmental factors like temperature extremes, direct sunlight, and moisture protection would be necessary.
