• Inspect for welding flaws by measuring the bead shape.
• Accumulate and output the profile data. Greatly simplify the management 
of welding bead quality.
• The high-speed 10-ms measurement 
period allows 100% in-line inspection.
• Automatic light intensity (brightness) 
adjustment provides stable measurement of fluctuating metal surfaces.
• The compact sensor head contains 
both the transmitter and receiver, so 
mounting space is not an issue.

Note: 1. The minimum light intensity at the edges of the beam is defined as 1/e2 (13.5%) of the intensity at the center of the beam. Some light will
scatter beyond this beam region and the measurement may be affected if the immediate vicinity around the workpiece is highly reflective.
2. This is the error with respect to the theoretical line of the displacement output when measuring the standard OMRON quartz glass. The
linearity may vary depending on the workpiece being used.
3. This is the error with respect to the theoretical line of the displacement output when measuring a standard OMRON stainless-steel block.
The linearity may vary depending on the workpiece being used.
4. This is the error with respect to the theoretical line of the displacement output when mea-
suring the standard OMRON white alumina ceramic. The linearity may vary depending on 
the workpiece being used.
5. This is the displacement output’s peak-to-peak displacement conversion value. These fig-
ures are for measurement of the standard OMRON quartz glass (mirror reflection) or standard OMRON stainless-steel block (diffuse reflection) at the center of the measurement 
region. The resolution performance characteristics may not be met when operating in a 
magnetic field.
6. These figures are for Sensors connected to a Z510-WC10E or Z510-WC15E and averaged over 16 measurements. The averaged data
was transmitted to a PC through an RS-232C connection for storage and processing.
7. This is the displacement output’s peak-to-peak displacement conversion value. (These figures are for measurement of the standard OM-
RON white alumina ceramic at the center of the measurement region.) 
The resolution performance characteristics may not be met when operating in a strong magnetic field.
8. These figures are for Sensors connected to a Z510-WC10E or Z510-WC15E and averaged over 64 measurements. The averaged data
was transmitted to a PC through an RS-232C connection for storage and calculations.
9. This is the value measured when the gap between the Sensor and workpiece (white alumina ceramic) is fixed with an aluminum jig.
