Devices and Radiological Health) registration has been completed. (Accession Number : 1220690)
*2. The values were measured using the OMRON standard sensing object (white paper).
*3. Defined as 1/e2 (13.5%) of the central light intensity at the measurement distance.
The spot diameter is sometimes influenced by the ambient conditions of the workpiece, such as light that leaks from the main beam, if the reflection factor of the
area surrounding the workpiece is higher than that of the workpiece.

The Sensors are influenced very little by the surface

The Sensors are influenced very little by the color of the
workpiece, so readjustment is not necessary when
switching to a different color of cable.

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/e2 (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.
