W4-3 Glass, Photoelectric retro-reflective sensor

At a glance
• Fast and reliable setup via teach-in pushbutton
• Continuous threshold adjustment technology to detect objects in changing
   conditions such as temperature, contamination and reflector wear
• Versions without polarizing filters to better detect depolarizing objects such as
   PET bottles, CD sleeves and shrink-wrapped, glossy objects

Your benefits

• Flat housing design eliminates alignment or mounting brackets, which saves time
   and money
• Low-cost machine integration due to small dimensions that enable mounting in
   areas with space restrictions
• Quick and easy setup due to highly visible intensive light spot
• The PinPoint LEDs well-defined, intense light spot simplifies alignment
• Nearly all transparent objects can be reliably detected
