Photoelectric sensors
W2S-2, Photoelectric retro-reflective sensor, autocollimation
Type
Part No.
> WL2S-2N1330
> 1064595
At a glance
• Sensing ranges of up to 1.2 m
• Reliable use on reflective tape with a high operating reserve
• No blind spots even at short distances thanks to autocollimation
• Reliable, universal object detection thanks to polarization filter
• Immune to optical interference
Your benefits
• Space-saving integration and extremely small reflectors in rails, joints and gaps
• Increased productivity due to highly repeatable switching points
• PinPoint 2.0 technology for a bright, small, and precise light spot, enabling quick
and easy sensor alignment
• Simple and cost-effective machine design since the sensor can see through small
drill holes and reflective tape can be used
• High reliability and long-term use in machines thanks to a rugged housing and a
45° cable outlet
