The W12 photoelectric sensors can be used nearly anywhere for exact object detection in demanding environments. Whether you are working with lasers, infrared light or LEDs – the photoelectric proximity sensors, photoelectric retro-reflective sensors and through-beam photoelectric sensors are suitable for a wide range of applications. The sensors are insensitive to shocks and vibrations thanks to their zinc die cast housing. IO-Link and BluePilot allow for fast and simple parameterization. Numerous functions such as background or foreground suppression ensure extremely reliable detection of transparent or very dark objects and make the W12 resistant to interference. Condition-based maintenance based on sensor and diagnostic data reduces costs and increases efficiency.

The W12 devices are genuine all-rounders. The portfolio comprises photoelectric proximity sensors, photoelectric retro-reflective sensors and through-beam photoelectric sensors with laser technology, PinPoint LED or infrared light. Different sensing ranges, switching frequencies, and connection options ensure almost limitless selection and combination possibilities. W12 sensors, for example, can be perfectly tailored to the equipment system and the requirements of the specific application – regardless of whether it be a packaging technology, automotive, logistics, pharmaceutical or beverage application.
Single device for everything: The W12 product family is the universal detection solution for a large number of industrial applications and industries
Incredibly easy – installation and commissioning using BluePilot
Set up and aligned in seconds: Using the BluePilot operating concept. The blue LED provides immediate feedback on whether the sensor is aligned correctly. The W12L devices with laser technology can be quickly and precisely parameterized using a Teach-Turn adjustment. While doing so, the LED display serves as an orientation aid for the desired sensing ranges or for assistance, thereby ensuring a very high operational safety. The device is especially easy to mount because the mounting holes offer different fastening options.
Uncomplicated mounting, fast parameterization: The W12 devices save you valuable time during commissioning
High flexibility – with just one device
The WTM12L variants come with a MultiMode feature: Various operating modes such as background blanking, foreground blanking, two-point teach-in, two independent switching points or window teach-in can be set directly on the device or via IO-Link. It is also possible to read the distance value from the device. The advantage: The same sensor can meet a wide variety of detection requirements. This means, for example, that the settings can be adjusted with a single action when changing the product. It is no longer necessary to replace the sensor.

Reliable detection – even at a large distance
In certain applications it necessary to detect objects over large distances. Using the W12L, especially large sensing ranges can be implemented thanks to the precise and powerful laser light. Furthermore, the optionally selectable ApplicationSelect operating mode provides even greater reliability when detecting dark and obliquely-oriented objects from a long distance.
Large sensing range, low error risk: The high performance laser optics of the W12L makes it possible to reliably detect even distant objects
Everything under control – with IO-Link
Thanks to IO-Link and comprehensive diagnostic functions, the status of the W12 photoelectric sensors can be viewed in real time. This enables faults, e.g., due to vibrations or contamination, to be detected early during operation as well as condition-based scheduling of maintenance, thereby avoiding downtimes and reducing costs.
Ready for Industry 4.0: Using the W12 and IO-Link, you can automate your production in diverse ways and make it especially reliable
Rugged metal housing – for very high resilience
SICK uses only zinc die cast metal housings for its W12 photoelectric sensors. This makes the sensors impervious to aggressive chemicals, high temperatures, dust, and water spray. The W12 effortlessly withstands shocks and vibrations due to machine movements or high-pressure cleaning. A high EMC resistance also protects the electronics of the sensors.
Withstands all stresses: Thanks to the rugged metal housing, the W12 is suitable for demanding tasks in harsh environments
Reliable data – even for transparent objects
From PET bottles right through to transparent films – the W12G photoelectric retro-reflective sensors reliably detect highly transparent and semi-transparent objects thanks to PinPoint technology. The focused light spot has a higher light intensity and is impervious to sources of interference in the production environment. In case of contamination, the switching threshold of the sensor is automatically adjusted via an AutoAdapt function. This extends the sensor availability and lengthens the maintenance interval, thereby increasing the productivity of the system. After cleaning, the sensor automatically restores the original switching threshold.
