Pepperl+Fuchs introduces WTS10 Weld Cap Sensors. These diffuse mode sensors check the quality of welding cap fronts and detect faults such as inclusions, faulty dressing, or burrs. These sensors provide high stability against discrepancies in the position and angle of the welding cap. They check upper and lower welding caps simultaneously and provides weak signal indication for proactive maintenance to help improve welding productivity. A push button teach mode facilitates quick and easy sensor programming.

"WTS10 sensors are an improvement over related sensor products for evaluating weld cap quality because they provide increased switching accuracy, and can detect even the smallest deviations. They also deliver a larger, more consistent light spot diameter and parallel beam path to evaluate every spot on the welding cap equally, for maximized repeatability and accuracy," says Tom Corbett, Product Manager.

WTS sensors feature a scratch-resistant mineral glass lens and provide superior position (± 2 mm) and tilt angle tolerance (± 1.5°). They also provide a consistent detection range of 2 – 12 mm regardless of the length of the welding cap, or whether the welding cap is brand new or a fully dressed tip. Highly visible LEDs provide quick and easy-to-understand status indication for "good," "pre-fault," and "fault" weld tip status.

Coaxial optics with parallel beam path, a new display concept with easy to read and understand status indication, greater switching accuracy, a uniform light spot over the entire sensing range, and a high positional and tilting angle tolerance characterize the sensor.
