Product Description
The SICK WL12G-3O2431 is a retroreflective photoelectric sensor engineered for high-performance industrial object detection, including transparent materials. This sensor features a block-style metal housing and utilizes LED-based retroreflective sensing to reliably identify items on conveyor lines, within automation machinery and for part counting.
With a 4-meter maximum detection range, the WL12G-3O2431 supports robust operation in production and handling systems, even for clear or non-opaque targets. Its clamp-mount design suits machine frames, robotic pick-and-place systems and quality inspection setups where quick and accurate detection is critical.
The integrated M12 connector with a 4-pin layout offers straightforward interface with controllers, I/O modules and junction boxes, providing seamless control integration. A PNP switching output delivers easy transistor-based interfacing, enabling sourcing of 100 mA maximum current for typical downstream automation inputs. The sensor allows for fast detection with a response time of just 330 microseconds, making it suitable for high-speed applications.
The rugged zinc die-cast metal enclosure provides long-term durability for industrial environments, certified to IP66, IP67 and IP69K ingress protection ratings. This ensures resistance to dust, water and even high-pressure, high-temperature washdown procedures, as required in food, beverage and pharmaceutical manufacturing settings.
The WL12G-3O2431 functions reliably in a broad operating temperature range from -40°C to 60°C, suited to both cold and warm installations. Its LED-based sensing, combined with retroreflective target detection, enables effective performance for transparent object sensing, quality inspection, sorting and robotic automation.
Applications include conveyor line sensing, industrial automation, robotics, quality inspection, material handling, and production machine integration. The sensor is clamp-mounted for flexible installation and is used where robust washdown and transparent target detection are required.
