Weld Seam Detection Sensor
NS9N-AAD-SC
Weld Seam Detection in narrow steel strips
for magnetizable steels as well as for
austenitic stainless steel

THE ROLAND PLUS
► Very high detection reliability
► Independent from optical surfaces
► Detection of invisible weld seams

● Suitable for narrow steel strips
● Independent of optical surface discolorations
● Also suitable for start and stop processes
● Analog outputs 4 to 20 mA or 2 to 10 V for the
connection to the PLC

● Cost-efficient control unit XA100-S
● Two different operating frequencies are
selectable

The Roland Company has now developed a new Weld Seam Detector
based on the eddy current principle for these type of semi-finished steel strips.
The system consists of a magnetizing unit and an eddy current encircling coil sensor that can be directly connected
to the PLC. The orifice of the encircling coil is suitable for material with the dimensions 1.575 in x 0.315 in.
In ferromagnetic materials, the premagnetization increases the process reliability of the system.
