Details

Precise miniature photoelectric sensors for use in tight installation spaces
Miniature photoelectric sensors of the W2 product family combine precise object detection with high operational safety. The powerful optics of the W2 feature an outstanding size-to-sensing range ratio. This means it can even detect jet-black objects precisely. The miniature photoelectric sensors are available in either slim or flat housings versions and, thanks to their very small design, can be integrated easily and compactly even in systems that are difficult to access.

-Configuration options via IO-Link technology

ADVANTAGES
Precise object detection – even with deep black objects
Miniature photoelectric sensors from the W2 product family are characterized by their precise object detection and high optical reliability. The sensors also reliably identify deep black or reflective objects.


The precise switching behavior and high detection quality enable universal object detection


The PinPoint LED ensures repeatable and precise detection of objects


The powerful optics make it possible to detect even deep black objects with a reflection factor of 1%

Space-saving integration and easy operation
Machines and systems are becoming more and more compact. Miniature photoelectric sensors of the W2 product family can be integrated where installation space is tight. The miniature photoelectric sensors are available in either slim or flat housing variants, making them particularly flexible to install. In addition, the integrated PinPoint LED makes alignment and commissioning of the sensor easy.


The compact sensor housing can be easily installed into very tight spots to save space


The highly visible, uniform light spot facilitates sensor alignment and commissioning


The sensor can be quickly and easily mounted directly on machine parts

Everything under control thanks to with IO-Link
Miniature photoelectric sensors from the W2 product family have extensive diagnostic and remote setting functions that can be used, for instance, to program the sensing range with millimeter precision and to check the quality of the settings at any time. Thanks to IO-Link, the sensors no longer have to be accessible for parameterization and monitoring, which is particularly beneficial for sensors installed close to one another. Individual sensor variants are also equipped with automation functions such as counting functions, debouncing and time stamp.
