Can the analog output model of light convergent reflective type Optical Sensor B5W-LB distinguish different kinds of objects?
Light convergent reflective type Optical Sensor B5W-LB series cannot distinguish between the kinds of objects that are sensed.
Distinguishing the type of sensing object means discriminating the difference in the amount of reflected light (the amount of light received by the sensor) from the various sensing objects. The light convergent reflective type sensor B5W-LB series has an optical lens design that can detect even small amounts of reflected light from various sensing objects such as black and transparent glass. As a result, while various objects in the sensing area can be detected, it is not suitable for use in determining the type of sensing object.
If you want to determine the type of sensing object, we recommend that you consider a fiber sensor with a digital display of the receiving light level, a fine adjustment of the threshold, and a variety of detection heads. If you want to determine the difference in the surface conditions of the sensing object (glossy and rough surfaces), you can increase the difference in the receiving light level (which is actually determined by the ratio, not the difference) by installing the reflective fiber head at an angle to the detection surface. Fiber sensors include E3NX-CA for color discrimination and E3X-SD for low cost.
