The Sick WS/WE100L-F2131 is a high-performance miniature through-beam photoelectric sensor designed for reliable object detection over long distances. This sensor pair, consisting of a sender (WS100L) and a receiver (WE100L), utilizes a precise Class 1 laser light source, providing an extensive sensing range of up to 60 meters. The highly visible, small laser light spot simplifies alignment, even over great distances. Its compact, rugged housing makes it ideal for installation in space-constrained applications, such as in packaging, logistics, and assembly automation. The sensor features a PNP switching output with selectable light/dark switching, offering flexibility for various industrial control tasks.
