W9 Series Compact


SICK W9-3 photoelectric sensors offer precise detection of small objects and object features. Reliable for use in harsh industrial environments: The W9 photoelectric sensor family has a rugged VISTAL™ housing with very high mechanical stability and therefore high sensor availability. The use of glass-fibre reinforced plastic combined with high-performance adhesives ensures excellent housing sealing and making it resistant to cleaning agents.

W9 sensors achieve high sensing ranges thanks to the PinPoint LED and laser technology. 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.

The portfolio contains photoelectric proximity sensors with excellent background suppression, photoelectric retro-reflective sensors with autocollimation optics and through-beam photoelectric sensors. The W9 thereby offers the right principle of operation for any detection task.

Features and Benefits


· Precise detection of small objects and object features
· Detection of objects even through small openings
· Less machine downtime thanks to a rugged VISTAL housing
· Best-in-class background suppression for photoelectric proximity sensors
· Slotted mounting options making fine adjustments on the screw possible
· Highly visible light spot that is unaffected by peripheral light and simplifies alignment
· Reliable detection for a diverse range of objects

Application Examples


· Detection of the smallest workpieces 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

Note

For retro-reflective sensors a suitable reflector is required.
For PL80A, PL30A & C110 reflectors see stock nos. 265-2776, 265-2760 & 265-2748 respectively.
