SICK Through Beam Photoelectric Sensor, Miniature Sensor, 60 m Detection Range

For the best possible performance in a wet environment: thanks to high light immunity, the new W4SL-3 Inox miniature photoelectric sensors from SICK with precise laser light spot set new standards when it comes to preventing undesired background reflections and to ambient light immunity, even in modern energy-saving lights. The combination of SICK's latest proprietary laser andASIC technologies reduces incorrect switching. The photoelectric sensors complete this product family. One device can reliably detect all transparent objects as well as tiny non-transparent objects. This reduces the variety of devices and saves on storage costs.

The photoelectric sensors also feature an IO-Link function, so that initial system performance diagnostics can be done independently. The W4SL-3 Inox is certified in accordance with ECOLAB. The membrane teach-in pushbutton and the pin-cast electrical connections make it reliable even in critical ambient conditions.

Precise laser light spot, laser class 1
Stainless steel housing with wash-down design
Latest SICK proprietary ASIC and laser technologies for outstanding background suppression and ambient light immunity
Teach-in pushbutton can be switched between detection of transparent and tiny non-transparent objects
ECOLAB certified, tested to IP 66, IP 67, IP 68 and IP 69K enclosure rating
IO-Link (optional)

Precise laser light spot for highly accurate switching
Washable stainless steel housing reduces bacterial contamination
Innovative wash-down design with sealed connections and unique patented membrane teach-in pushbutton
High ambient light immunity reduces incorrect switching and ultimately machine downtime, even when modern energy-saving
lights are used
The highest degree of machine design flexibility. Outstanding BGS (background suppression) eliminates the effect of undesired
background reflections. Auto collimation permits detection through very small drilled holes.
IO-Link provides effortless initial diagnostics of system performance

Precise object positioning – Detection of slices of sausage before primary packaging on a coarse-meshed, hygienic conveyor
Precise edge detection – Controlling the exact position of ampulla-tubes before final closing
Application are mostly in the pharmaceutical industry but also e.g. at the packaging, electronic and solar industry as well as food
and beverage industry
