Brand: SICK
Model: WTB4FT-21311120ZZ
Type: Photoelectric Proximity Sensor
Introduction:
The miniature sensor is the perfect complement to the product range of a new generation of opto-electronic sensors such as the W16 and W26. This allows for versatile use in a wide range of challenging installation situations. The W4F is a high-performance application specialist: Background suppression is improved, and flat, highly reflective and transparent objects are detected even more precisely. In addition, the W4F as Smart Sensors make monitoring and diagnostics easier than ever before and enable future-proof use in I4.0 plants.
- Technologies: Foreground Suppression, DoubleLine, V-optics and MultiSwitch
- Two switching points and distance value output in one device
- Diffuse sender LED for ambient light suppression
- Blue Pilot: Teach-Turn adjustment with optical sensing range and alignment aid
- Smart Sensor: Latest diagnostics and monitoring functions
- VISTAL® housing
- Solution for particularly challenging detection tasks in tight installation spaces.
Extremely high dependability due to strong background suppression and superior transparency, highly reflecting, and flat object detection.
Two switching points as well as the output of distance values expand the application possibilities.
Flexible use thanks to high optical reliability.
The highly visible light spot combined with the intuitive Blue Pilot operating interface enables set-up in mere seconds.
Maximum monitoring and process reliability thanks to intelligent monitoring and predictive maintenance.
