The E39-RS3 is a tape-type reflector for use with retroreflective sensors, such as those in the OMRON E3Z family. When paired with an E3Z-R series sensor, it facilitates a rated sensing distance of 1.4 meters. For reliable operation, a minimum distance of 150 mm must be maintained between the sensor and the reflector. As a tape reflector, it provides flexible installation for object detection in various industrial automation applications.
