SICK Retroreflective Photoelectric Sensor, Block Sensor, 1.2 m Detection Range

The ultra-compact WL2SG-2 miniature photoelectric sensor for detecting transparent objects offers features that were previously only available with much larger sensors. Ampules, foil and glass are reliably detected in the most confined of spaces. The WL2SG-2 is adaptable: dust on the reflector or wear is compensated for in the same way as temperature changes and changes in light intensity. The WL2SG-2 is not only adaptable with regard to harsh industrial environments – settings for the respective application can also be selected via IO-Link.Special operating modes for gaps in the bottle flow or for foil tear monitoring are available for extreme operating conditions. The W2S-2 offers optimal performance with an ultra-compact design for use in both pharmaceutical or automatic assembly machines.

The newest automation innovation is already on board. Configuration and diagnostics are set via the control in the same way as continuous monitoring.

Extremely high sensor size to sensing distance ratio
High switching point accuracy
Teach-in functions enable reliable settings
Automatic switching threshold adaption
Single-lens autocollimation for visibility through apertures and drill holes
Flexible sensor settings, monitoring, advanced diagnostics, and display thanks to IO-Link

Machine design flexibility: the ultra-compact sensors offer above-average sensing distances and provide space-saving installation
Remote setup: sensors installed in confined spaces can be set and monitored remotely via IO-Link.
High operational reliability and system throughput: all familiar, highly-transparent objects are reliably detected
Precise switching characteristics and a high detection quality guarantee an universal object detecting
Universal use: conventional mounting and housing design
The precise light spot of the PinPoint 2.0 LED enables the use of very small reflectors and reflector surfaces

Detection of transparent ampules and vials in the pharmaceutical industry
Detection of glass in window production
Detection of displays throughout the entire production process, from the pure, highly-transparent substrate to the finished display
Detection of preforms in beverage technology and of the smallest gaps between preforms for counting purposes
