Photoelectric sensor Sick W27 ,Ready to use in zone 2 and 22 Ex areas thanks to device category 3G / 3D
W27 photoelectric sensors are suitable for use in a harsh industrial environment. The powerful sensors are designed to withstand strong vibrations, shocks or strong temperature fluctuations. The devices offer a high operational reliability even with reflections. There are also ready-to-install sensor variants with additional protective metal housings that meet the requirements of device categories 3D and 3G according to ATEX. This enables these variants to achieve a mechanical stability that is unmatched by standard sensors.
Features
- Sensor variants with additional protective metal housing that meet the device categories 3G and 3D (optionally certified to IECEx and CCC Ex)
- PinPoint LED with well-visible, uniform light spot
- Powerful background suppression and high ambient light immunity
- Vibration resistant and reliable operation at temperatures down to −20 °C
Benefits
- Versatile use in harsh environments, protective metal housing especially suitable for explosion-hazardous areas
- High user-friendliness through easy alignment, commissioning and monitoring
- Fault-free system operation thanks to reliable object detection
- Operational safety thanks to high resistance to harsh ambient conditions
