Panasonic RX-LS200 adjustable Range Reflective Photoelectric Sensor does not detect the background beyond the set distance since it is of distance adjustable type. The color or size of the object does not affect its sensing performance. Its robust enclosure is made of die-cast zinc alloy. The equipment on which the sensor is mounted can be washed without any problem. The sensing performance is less affected by dust as it does not depend on the incident light intensity. It can be used on a high speed assembly line. The sensing range for which the sensor detects an object is determined by the incident beam angle, regardless of the incident light intensity.
