Highly precise and not sensitive to any source of light interference

Reliable detection of the smallest objects The extremely small light spot of the W4SL-3 miniature photoelectric sensors provides the ideal starting point for precise object and product detection in automation. It makes the sensors ideal for precise position, presence, overhang and height checks involving the smallest objects, even under critical light conditions. The precise laser light spot supports switching with maximum accuracy, thus providing the basis not only for optimum product quality but also for reduced machine downtime as there are fewer switching errors.

Versatility for many industries W4SL-3 miniature photoelectric sensors are perfect for the packaging industry, the automotive and part supplier industries, the electronics industry and the solar industry. But that's not all: they even deliver optimum results in machine tool building, in the food and beverage industry, and the pharmaceutical industry. Applications include examining grippers in the automotive industry, inspecting dies in machine tool building, or edge detection of semiconductor wafer carriers.

W4SL-3 miniature photoelectric sensors: High performance for high expectations

With their precise laser light spot, the new W4SL-3 miniature photoelectric sensors are setting new standards by providing high optical immunity to undesired background reflections and immunity to ambient light even from modern energy-saving bulbs. They also are impressive with maximum mechanical and electromechanical ruggedness.

Reliable switching in all environments

Lowering costs and creating new solutions

The photoelectric proximity sensors in the WTB4SL-3 product family outperform all other laser sensors currently available on the market. In everyday production, they have absolutely no sensitivity to all active and passive sources of light interference. High-frequency lights or any type of reflection, reflective metal surfaces, windows or high-visibility vests – none of these sources of optical interference will trigger a switching signal incorrectly from a WTB4SL-3 photoelectric proximity sensor. Accordingly, these sensors reduce incorrect switching and avoid consequential machine downtime.

Best-in-class performance for background suppression creates maximum freedom in machine design, as changing and reflective backgrounds or dead spots no longer pose a problem for the application.

Maximum optical ruggedness thanks to innovative ASIC technology

State-of-the-art technology in a miniature size Available exclusively in the photoelectric proximity sensors in the W4SL-3 product family, the ASIC developed by SICK meets very stringent requirements where detection quality is concerned. Where ruggedness of ambient light and r eflections is concerned, the ASIC is unrivaled by other products. Furthermore, it is incredibly resistant to shock and v ibration. These properties also significantly reduce instances of incorrect switching and machine downtime.

W4SL-3 miniature photoelectric sensors: The best clear object detection in their class

The photoelectric retro-reflective sensors in the WL4SLG-3 product family stand out in their class with the best detection performance for transparent glass and plastic objects –all with just one device. They provide the ideal starting point for efficient and automated production.

Duo mode: One sensor for two applications WL4SLG-3 photoelectric retro-reflective sensors are supplied as standard with a switchable operating mode for detecting transparent objects and a mode with non-transparent objects can be detected. Simply press a button to switch between the two user modes. A single device can detect, for example, not only transparent vials and PET bottles but also metallic needles and wires, thus reducing the variety of sensors and their storage costs.

Fully automatic: adaptation to contamination

Absolutely reliable: detection of clear objects

The photoelectric retro-reflective sensors in the WL4SLG-3 product family automatically adapt to changing light conditions. If dust or dirt collects on the sensor lens over time, the microprocessor responds to the reduced incidence of light and adjusts the switching threshold accordingly. Once the sensor lens has been cleaned, the original signal level is restored automatically – representing a significant reduction in main tenance time and costs from all angles.

The aim: best possible performance in clear object detection. The solution: the SICK photoelectric sensor package, comprising the innovative ASIC, an autocollimation lens, and two polarizing filters. Thanks to these features, the WL4SLG-3 photoelectric retro-reflective sensors are able to offer the best detection of transparent or shiny surfaces and objects in their class. They are able to detect clear glass surfaces just as reliably as small vials, tape edges, and PET bottles.

A laser sensor must be capable of quality in every millimeter

Stable housing, proven mounting Systematic production and testing procedures safeguard the high mechanical quality of the sensor. A compact plastic housing measuring 19 x 12.2 x 17.3 mm (H x W x D) encases all W4SL-3 miniature photoelectric sensors. The hole spacing is the same as is featured on the W4S-3 mounting system, which is already successful in the automation.

Reliable thanks to high EMC safety The high-quality design and manufacture of the housing conti nues with the electronics inside the sensor: W4SL-3 miniature photoelectric sensors with laser technology are impressive with high insensitivity to all kinds of electromagnetic interference.

IO-Link: The world as seen by a sensor The W4SL-3 miniature photoelectric sensors with laser technology also feature IO-Link technology, meaning that they can be used for initial diagnosis of system performance. Additional functions such as meters or profile detection can be integrated directly into the sensor, rendering complex programming of controllers unnecessary. Further advantages: • Exact and precise configuration • Support of remote control and remote monitoring • Straightforward transfer of analog values • Wire break detection • Can be connected to any fieldbus • Predictive error detection • Intelligent additional functions in the sensor


W4: Small but mighty The new W4SL-3 sensors are part of the established W4 range of photoelectric sensors from SICK. In addition to making it very easy to implement custom solutions, the W4 sensors are impressive due to their ability to reliably detect transparent objects. Their PinPoint technology f acilitates the combination of commissioning that couldn't be easier with very high levels of performance. What's more, stainless steel housings make for maximum ruggedness through tightness in harsh environments. For all you need to know about W4, visit www.sick.com/de/w4-3united.

Quality with long sensing range

Product description The WL4SL-3 photoelectric retro-reflective sensor has a long sensing range of up to 12 m. The highly visible homogeneous laser light spot has a sharp contour to facilitate alignment. The photoelectric sensors use autocollimation technology to ensure that the sensor also reliably detects close-range objects. This technology also enables detection through nar-

row gaps or very small drilled holes. The photoelectric sensors also provide an IO-Link interface to allow performing initial system performance diagnostics. In addition, IO-Link permits the integration of additional functions such as meters directly into the sensor. There is no need for complex control programming.

WSE4SL-3



Reliable object detection at extended ranges

Product description The WSE4SL-3 through-beam photoelectric switch reliably detects objects even at long distances of up to 60 m. The switch’s precise, highly visible laser light spot has a sharp contour, enabling

highly accurate switching and facilitating alignment. The sensor’s high precision also makes it suitable for applications requiring the laser beam to be guided through small openings or holes.

At a glance •• Precise laser light spot, laser class 1 •• Long-range detection up to 60 m •• Established and proven housing design

•• High-quality sensor manufacturing and testing for mechanical ruggedness •• Choice of adjustment via teach-in button, 5-turn potentiometer, or cable

Your benefits •• Highly visible, even laser light spot with a sharp contour to facilitate alignment •• Long sensing range allows use up to 60 m

•• Sender-receiver system ensures high reliability

•• Established and proven housing design for easy installation
