Instruction Manual |
Note: Incorrect detection may occur outside the measurement range if the object has a high reflection factor.
*1. These Sensors are classified as Class 1 laser devices under IEC 60825-1 and the regulations of Laser Notice No. 50
for FDA certification.
CDRH (Center for Devices and Radiological Health) registration has been completed. (Accession Number:1220691)
*2. The values were measured at the center of the sensing distance using OMRON’s standard sensing object (white
ceramic).
*3. Spot diameter: Defined as 1/e
2 (13.5 %) of the minimum diameter (actual value) in the measurement range.
False detections can occur if there is light leakage outside the defined region and the surroundings of the target
object have a high reflectance in comparison to the target object.
Also, correct measurement values may not be obtained if the workpiece is smaller than the spot diameter.
