Type
Part No.
> WTB2S-2N3130
> 1064581
At a glance
• Sensing ranges of up to 150 mm
• Almost no black/white shift up to 60 mm
• Sensor with line-shaped light spot
• Sensor with laser-like focused light spots
• Precise background suppression that is immune to interference/crosstalk
• High-performance PinPoint 2.0 LED
Your benefits
• An ultra-compact design with the performance of large photoelectric proximity
sensors offers new space-saving machine construction possibilities.
• Large variety of proximity sensors and operating concepts enable a wide range of
application options
• Use in confined spaces: detection of small, flat parts thanks to high-quality
background suppression and almost nonexistent black/white shift
• Remote access: models with IO-Link allow data to be easily accessed from the
PLC
• High availability and long-term use in grippers thanks to flexible and rugged cable
entry
