Reliable detection even of reflective safety vests

Stationary work areas and travel paths of industrial trucks are overlapping more and more in production processes. That is why workers or machine operators are more frequently wearing reflective safety vests to increase occupational safety. However, the reflective warning stripes can cause optical sensors to malfunction if the vests enter the fields of view of the sensors. In spite of its small size, the W4F photoelectric proximity sensor is very powerful and can actively detect and blank interfering backgrounds thanks to a second sender LED. The W4F photoelectric proximity sensor detects deep black, highly reflective and transparent objects of all types.
