E3NC-SH100/SH250
E3NC-SH100/SH250
Laser Amplifier Units (CMOS Type)
E3NC-SA
* Based on November 2012 OMRON investigation.
The background is used as a reference to detect everything but the reference. The surface conditions or inclination of the workpiece do not influence detection, so stable detection is maintained without changing the settings even if the workpiece is changed.
Easy Adjustment after Head Installation
Easy-to-understand Distance Display (*Target)
You can see the distance at a glance, which simplifies adjustment. After Head installation, you can reduce adjustment time after line switchovers and reduce line stoppage time.

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 at the 1/e2 (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.
Also, when detecting a workpiece that is smaller than the spot diameter, a correct value may not be obtained.
