The SICK WLG4S-3E1134V (Part No. 1048027) is a versatile photoelectric sensor from the G4S family, designed with energetic mode detection for dependable performance in a wide variety of industrial automation tasks. Combining compact size, reliable functionality, and robust construction, this sensor ensures high accuracy in detecting objects across different shapes, colors, and surface finishes.

Operating in energetic mode, the WLG4S-3E1134V functions by detecting light reflected directly from an object, making it a strong choice for standard applications where foreground suppression or background suppression may not be required. This detection principle offers a cost-effective yet highly dependable solution for tasks such as part positioning, packaging verification, or conveyor object counting.

The sensor incorporates a visible red LED emitter, which allows for simple setup and alignment. The clear, bright light spot enables operators to easily confirm the detection area, reducing installation time and ensuring accurate positioning within complex machinery or compact layouts. This feature minimizes commissioning errors and enhances operational efficiency.

One of the defining benefits of the WLG4S-3E1134V is its fast response time, which allows it to detect small or fast-moving objects with precision. This is particularly valuable in dynamic environments such as packaging lines, filling machines, or logistics systems, where precise timing is essential to maintaining high throughput and reducing production errors.

The housing design reflects the G4S series’ balance of compactness and durability. The slim body makes it suitable for installations with limited space, while its robust build ensures it can withstand the mechanical stresses common in continuous industrial use. With an IP67 protection rating, the sensor is resistant to dust and water ingress, allowing for dependable operation in demanding conditions, including environments where frequent cleaning or exposure to moisture is expected.

Electrically, the WLG4S-3E1134V features a PNP output configuration, allowing seamless integration into modern PLC-based control systems. The sensor operates on a 10–30 V DC supply range and includes built-in protective features against short-circuits and reverse polarity, ensuring both safety and reliability during long-term use.

In real-world applications, the WLG4S-3E1134V is well-suited for industries such as material handling, food and beverage, packaging, and general manufacturing. It reliably detects items regardless of their surface characteristics, offering flexibility and performance that enhance automation reliability.

In conclusion, the SICK WLG4S-3E1134V combines energetic mode detection, visible red LED guidance, fast response time, and rugged IP67 protection into a compact, industrial-ready sensor. It is a dependable choice for applications demanding consistent object detection with ease of setup and long-term operational stability.
