Ratings and Specifications
Compact Laser Sensors: E3NC-L
Sensor Heads
*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.
E3NC-LH01, E3NC-LH02 (Accession Number: 1220690)
E3NC-LH03 (Accession Number: 1320739)
*2. The values were measured using the OMRON standard sensing object (white paper) for the E3NC-LH01, E3NC-LH02, and E3NC-LH02 + E39-P52.
The values for the E3NC-LH03, and E3NC-LH03 + E39-P51 apply when an E39-R21, E39-R22, E39-RS10, or E39-RS11 Reflector is used. Other Reflectors are
not recommended.
*3. Defined at the 1/e
2
(13.5%) of the central intensity at the measurement 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.
*4. Measured at the rated sensing distance.
*5. The E39-P5@ contains a packing to prevent entry of foreign matter. The degree of protection between the E3NC-LH@@ and E39-P5@ is not specified.
