Maximum performance for handling demanding detection tasks involving tiny objects. With its precise laser light spot, the W4SL-3 miniature 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.
