Consistent Operating Methods for All N-Smart Amplifier Units

Basic Tuning
Two-point Tuning

The larger incident level between measurements with and without a workpiece is set to 9,999.

Procedure

Press 3163_fe_8 once with a workpiece.
Press once without a workpiece.

The values are displayed together to immediately show changes in incident levels.

High-precision Positioning
Position Tuning

High-precision, pinpoint workpiece positioning is possible.

Procedure

Press 3163_fe_8 once without a workpiece.
Place workpiece in desired position and press for at least 3 seconds.

High-speed Workpieces
Full Auto Tuning

You can adjust to moving workpieces without stopping the line.

Procedure

Press 3163_fe_8 for at least 7 seconds without a workpiece. When 3163_fe_12 , appears on the green digital display, send a workpiece pass the Sensor. Release your finger after the workpiece passes.

Easy, Dependable Setup for Detection of Minute Moving Workpieces
Solution Viewer (PAT.P)

The passing time and difference in incident level are displayed when a workpiece passes. The display of the differences in incident level lets you determine if the threshold is the best. The display of the passing time lets you determine if the response time is best so that you can achieve reliable operation.

*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: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.
*4. Measured at the rated sensing distance.
