The W9 photoelectric sensor family offers a wider range of solutions than ever before. It is a complete product family, including photoelectric proximity sensors as well as photoelectric retro-reflective sensors and through-beam photoelectric sensors. All sensors are equipped with the latest laser and LED technology, protected by a rugged VISTAL® housing – for even stronger mechanical resistance. The W9 range works using SICK's SIRIC® technology

optical and electromagnetic interference is effectively suppressed in any environment. With the addition of various connection, mounting and sensing options, the W9 sensor family is the ideal solution for a variety of application needs in the automation environment.

Applications

Detection of the smallest work pieces or fine details on products
Detection through narrow openings
Checks for protrusions or misalignment
Detection of objects within a short distance from difficult backgrounds
Detection of transparent objects
Object detection in harsh industrial environments
