Reflection fiber optic sensor detection distance
Target detection is based on the amount of reflected light returned to the receiver. Because the detecting distances range from a couple inches to several meters, adjustment during installation is incredibly easy. Versatile Applications: This sensor is suitable for a wide range of applications, from factory automation to. Spot size and focal distance are adjustable, so there is no need to change the distance between the sensor and the target. This narrow beam helps avoid deflection and is suitable for detecting objects at longer distances.
