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
• Reliable and quick setting via the push of a button
• 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 LED's well-defined, intense light spot simplifies alignment
• Nearly all transparent objects can be reliably detected
