Photoelectric Sensor

The WTB4 multiline photoelectric sensor from Sick Inc. uses specially designed optics to create two line-shaped light spots to continuously detect objects with large gaps, such as PCBs, or products that are shiny or dark from leading edge to trailing edge. It is suitable for a variety of packaging and semiconductor applications.

To activate the output, both light sources must reflect light back to the sensor. Once both light sources have returned, the sensor will remain active, even if one of the beams is not returned. By using two light beams, the WTB4 can detect a variety of products that previously caused downtime resulting from incorrect detection from a single point sensor.

The device features Sick’s third-generation custom ASIC (application-specific integration circuit), which incorporates OES3 technology to provide background suppression. The technology also makes it possible to ignore shiny targets, detect multicolored objects and offer ambient light immunity.
