The SICK WL9-2P631 is a compact photoelectric sensor designed for through-beam applications. It consists of a separate transmitter (emitter) and receiver, providing highly reliable detection even in challenging environments with dust, steam, or varying object properties.
Through-Beam Principle: High immunity to environmental interference.
Long Sensing Range: Up to 2 meters (depending on model variant).
Red Light Beam: Visible for easy alignment.
Compact Housing: Small size for flexible installation.
IP67 Protection: Resistant to dust and water ingress.
Typical Applications:
Object detection on conveyors
Packaging machinery
Material handling systems
