The Sick WLG4S-3P3434 (Part no. 1046819) is a high-performance photoelectric sensor from the G4S series, designed for compact installation environments where reliability and precision are essential. Built with advanced optical technology and durable construction, this sensor is widely used across industries such as packaging, material handling, logistics, and assembly automation.

One of the key strengths of the WLG4S-3P3434 is its visible red light spot, which simplifies sensor alignment and commissioning. Operators can easily see where the detection field is positioned, making it straightforward to install the sensor in tight or complex machine layouts. Despite its small footprint, the sensor delivers a powerful and reliable detection capability.

The device incorporates background suppression technology, allowing it to reliably detect objects of varying colors, shapes, and reflectivities. This feature reduces false switching caused by reflective surfaces, glossy packaging, or changing ambient light conditions. As a result, the sensor provides stable performance even in environments where traditional photoelectric sensors might struggle.

With an extended sensing range of up to 400 mm, the WLG4S-3P3434 can handle a wide variety of detection tasks. Whether the application involves monitoring product flow on a conveyor, detecting objects in automated assembly lines, or verifying the presence of items in packaging systems, the sensor ensures consistent results. Its sharp and focused light spot allows for precise switching points, essential for high-speed processes.

The sensor is housed in a rugged enclosure rated IP67, offering protection against dust, water spray, and moisture ingress. This makes it suitable for demanding production environments where equipment may be exposed to harsh conditions. Its robust construction minimizes downtime and extends service life, ensuring dependable operation over long periods.

From a performance perspective, the WLG4S-3P3434 offers a PNP output configuration with fast response times. This ensures compatibility with a wide range of automation systems while providing reliable switching signals for fast-moving objects. The sensor is powered by a 10–30 V DC supply, ensuring energy-efficient operation and straightforward integration.

Ease of use is further supported by simple teach-in configuration, which allows operators to quickly set up detection thresholds. This reduces installation time and makes the device adaptable to multiple applications without requiring advanced technical knowledge.
