SICK Through Beam Photoelectric Sensor, Rectangular Sensor, 0 → 60 m Detection Range

Maximum performance for handling demanding detection tasks involving tiny objects. With its precise laser light spot, the W4SL-3miniature product family sets new standards by providing high optical light immunity from undesired background reflections and immunity to ambient light - even from modern energy-saving lamps. The combination of SICK's proprietary laser and ASIC technologies reduces incorrect switching to minimize machine downtime, reducing the variety of devices and saving on storage costs.

The photoelectric sensors also provide an IO-Link interface for initial system performance diagnostics. Furthermore, IO-Link permits the integration of additional functions such as meters directly into the sensor. There is no need for complex control programming.

Precise laser light spot, laser class 1
Teach-in pushbutton can be switched between detection of transparent and non-transparent objects
Sensing ranges between 25 mm and 60 m
Latest SICK proprietary ASIC and laser technologies with second emitter LED to provide outstanding background suppression
and ambient light immunity
Choice of adjustment via teach-in button, potentiometer, cable, or IO-Link

Precise laser light spot for highly accurate switching behaviour
High optical ambient light immunity reduces incorrect switching and thus machine downtime, even when modern energy-saving
lamps are used
The highest degree of machine design flexibility BGS (background suppression) eliminates the effect of undesired background reflections. In addition, auto collimation allows detection through small drilled holes
One device for detecting both transparent objects and the smallest non-transparent objects, thus reducing the variety of sensors
and saving on storage costs
IO-Link facilitates initial system performance diagnostics and uses additional sensor functions (optional) to reduce complex control programming

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
