ADVANTAGES

Diverse application possibilities thanks to different product variants
W4 photoelectric sensors are characterized by the range of individual variants available. With the ability to select from a variety of designs, you can obtain the most suitable sensor for your specific installation situation. Thanks to the compact sensor housing, the different designs can be integrated easily and in a space-saving manner even in very tight installation spaces. The availability of a variety of housing materials also opens up numerous applications. You also have freedom of choice when it comes to the light source. No matter what your particular application, SICK offers a reliable solution to precisely suit your specific requirements.


W4 sensors are available in either a Slim or Flat design. The standardized mounting ensures uncomplicated installation regardless of the design selected.


The sensors come with a housing made from either VISTAL or stainless steel. A hygienic stainless steel version is available for applications in sterile environments.


Red laser light provides the ideal basis for detecting even very small objects. The other light sources available are the highly-visible PinPoint LED, or an infrared LED.

Various designs, housing materials and light sources provide a great deal of flexibility when selecting the most suitable sensor for your needs
Impressive detection results in countless applications

Thanks to the integrated ApplicationSelect mode, the sensor functions can be adapted to the specific requirements of the application. Even objects in an oblique orientation or with a low remission factor can thereby be reliably detected.


The LineSpot technology ensures perforated, textured, and uneven objects can be reliably detected.


In the case of transparent objects such as glass bottles or cling film, the ClearSens technology guarantees reliable detection results.


The sensors can provide the distance value in millimeters and the remission value of the detected object via IO-Link.


Thanks to foreground suppression, the sensors reliably detect very flat, poorly remitting, reflective, and uneven objects.


The integrated v-optics technology helps the device detect highly reflective and transparent objects such as wafers or displays by means of a very small, laser-like light spot.

Thanks to innovative technologies, the sensors can solve the most demanding detection tasks in almost any application regardless of the object properties

High user-friendliness through easy commissioning and operation
Besides their high detection reliability, the latest generation of W4 photoelectric sensors stand out on account of their particularly easy handling. Thanks to the intuitive BluePilot operating concept, the sensors can be configured in a matter of seconds via a push-turn mechanism and tailored to the specific application. A blue LED indicator gives you immediate feedback on the optimal alignment of the sensor. If the detection quality drops due to contamination or vibrations, you are alerted to this via a well visible LED. This enables malfunctions to be correctly early, and unplanned system downtimes to be avoided.


Using a combination of teach-in button and potentiometer, the required settings can be easily configured directly on the device


The blue LED alignment aid accelerates the process of optimally aligning the sensor, and indicates any changes in the operational safety at a glance


Thanks to the intuitive operating concept, the mode selection can be effortlessly performed and read directly on the device

The BluePilot operating concept allows convenient commissioning of the sensor in just a few seconds. The operating concept also minimizes the risk of unplanned downtimes.

Increased productivity thanks to innovative functions
The latest generation of W4 photoelectric sensors acquire a variety of performance parameters such as temperature, operating hours, remission values and distances values. The acquisition of these parameters provides the foundation for automated condition monitoring, which enables unplanned downtimes to be avoided. You can also flexibly and precisely tailor the sensor settings to your application. Condition monitoring and adjustments help increase your machine productivity. W4 photoelectric sensors therefore offer a future-proof solution for your system.

Innovative monitoring and diagnostic features allow powerful process control and thereby increase the machine productivity
