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.
