Sick WL27X-3P3431 Description
- Marking: EX II 3D IP67 T70C, EX II 3G EEx nA II T4 X according to Directive 94/9/EC (ATEX)
- Corresponds to 3D/3G category
- Conform with standards and ready-to-install: Sensor + protective housing (stainless steel 1.4301)
- High scanning range, high operating reserves
- Red
- Reliable operation in industrial environments and when devices are mounted opposite one another
- Ready-to-install sensors conform with the 3G/3D category for explosive zones (ATEX)
- Less downtime plus resistance to contamination due to high operating reserves
- Extremely vibration resistant and therefore largely independent of ambient conditions
- Wide range of applications with respect to operating temperature: -40 C - +60 C
