WL4SLG-3F2234, Sick Retroreflective Photoelectric Sensor, Miniature Sensor, 4.5 m Detection Range

Overview

The stainless steel housing of the WL4SLG-3 Inox Hygiene photoelectric retro-reflective sensor, which is designed based on hygiene guidelines, is ideal for machines in which hygiene is already part of the design. The sensor mode can be switched between the detection of transparent and non-transparent objects at the touch of a button. This means that one device can be used to detect both transparent vials and metallic needles, for example. This reduces the variety of sensors needed. The precise, highly visible laser light spot ensures a high level of detection quality and facilitates alignment. Auto collimation technology ensures that the sensor can be relied upon to detect objects at close range as well as through small drilled holes.

The photoelectric sensors also feature anIO-Link function, so that initial system performance diagnostics can be carried out independently. Furthermore, IO-Link permits the integration of additional functions such as meters directly into the sensor. There is no need for complex control programming.
