Sick Retroreflective Photoelectric Sensor, Block Sensor, 4.5 m Detection Range

The WLG4-3 photoelectric retro-reflective sensor reliably detects transparent objects such as glass. Its small size is ideal for applications with limited mounting space. Adjusting these sensors can be done with the click of an easy-to-use teach-in pushbutton. Plus, these sensors don’t require any brackets, making them easy to mount directly to the machine – even in tight spaces.

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

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
