Overview The WL4SLG-3 detects all types of objects, including transparent vials, PET bottles, metallic needles, and wires, The precise, highly visible laser light spot ensures a high level of detection quality and facilitates sensor alignment. Autocollimation technology ensures that the sensor reliably detects objects at close range and through small drilled holes. The sensor uses automatic switching threshold adaptation to adjust automatically to changing light conditions, helping ensure maintenance-free system operation. The photoelectric sensors also provide an IO-Link interface to allow performing initial system performance diagnostics. In addition, IO-Link permits the integration of additional functions such as meters directly into the sensor. There is no need for complex control programming. At a glance Precise laser light spot, laser class 1
Teach-in button can be switched between detection of transparent and smallest non-transparent objects
Automatic switching threshold adaptation provides automatic adjustment to changes in light conditions
Sensing ranges up to 4.5 m
Autocollimation optics prevent blind spots
Choice of adjustment via teach-in button, potentiometer, cable, or IO-Link Your Benefit One device for detecting both transparent objects and the smallest non-transparent objects at sensing ranges up 4.5 m, thus reducing the variety of sensors and saving on storage costs.
Highly visible, even laser light spot with a sharp contour to facilitate alignment
The highest degree of machine design flexibility. Autocollimation permits detection even through small drilled holes.
High-quality sensor manufacturing and testing reduce maintenance costs
Established and proven housing design for easy installation
IO-Link facilitates initial system performance diagnostics and uses additional sensor functions to reduce complex control programming Applications Overhang control – sensor avoids overhanging panels
Precise object positioning – Monitoring the exact position of a part in order to prepare a quality check
Precise edge detection of glass panel
Monitoring additional features of a part such as boreholes
Check whether a part is located in the gripper of the robot
Application are, e.g. at the packaging, automotive and part supplier, electronic and solar industry, machine building and the industries of commercial goods
