E3NC
Ultra-compact CMOS Laser Sensor: E3NC-S
Sensor Heads
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 De-
vices 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. Beam size: Defined at the 1/e
2
(13.5 %) of the central intensity at the measurement center distance.
Measurement may be influenced 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, when detecting a workpiece that is smaller than the beam size, a correct value may not be obtained.
