Proximity sensor with V-optics to detect even flat, highly transparent, or glossy objects without a reflector, such as
Displays / plain windows / mirror like surfaces/ semi-conductor wafers
Highest reliability and highest operating reserve
Sensing ranges up to 36 mm
Flat/Glossy Object Detection
Proximity sensor with background suppression (that is immune to crosstalk and interference) and a 3 turn potentiometer
Sensing ranges up to 150 mm
Most precise adjustment via IO-Link or 3 turn potentiometer
Fixed/preset sensing ranges with a tolerance < ± 2 mm
Power to detect ultra black with R = 1 %
Industry Leading Crosstalk Immunity

7. W2S-2 Features and Benefits Continued
First miniature proximity sensor with a line shaped light spot that provides a highly accurate and repeatable switching point that is constant even for objects with gaps, groves or openings
Immune to interference/crosstalk
Sensing ranges up to 90 mm

9. W2S-2 TARGET APPLICATION – SMALL PART ASSEMBLY PART DETECTION IN A GRIPPER
Application overview
Detects that the part remains captured in the gripper.
Challenges
Shiny surfaces in background
Presence of other sensors in the background
Space and weight restrictions
Distance to the object
Variations in object size, color, transparency…
Solution
Advanced ASIC technology identifies and blanks optical disturbance from shiny objects or sensors in the background
Sensing distance up to 150 mm
PinPoint 2.0 concentrated or diffused light spots available
128 pixel sensor array allows to blank objects in the near background, down to 6 mm

10. W2S-2 Target Application Electronic Assembly Customer Challenges and Target Industries
Application overview
Verify the correct placement of sub-assemblies on a carrier
Challenges
Semi-automatic assembly or test stations, printed circuit board and other components have to be placed manually on the carrier. An incorrect or incomplete loading will affect quality and can damage the tools.
Space is limited and the features to be detected can be very small. The process should only start when all sensors are triggered to confirm that the parts are present and correctly positioned.
Solution
SICK miniature photoelectric switches are immediately ready for use without adjustment. Advanced background suppression ensures the sensors are unaffected by the machine background. Multiple sensors can be connected to the same input ,which greatly simplifies the wiring on the carrier, a major advantage over the fiber optic alternative.
Cross-talk mitigation in the sensor avoids the risk of disturbance from other sensors in background
Each sensor includes a status LED to provide feedback to the operator. Small-sized light spots, using SICK PinPoint technology, enable precise recognition of objects with a high level of repeat accuracy.
