Radar Sensors in Automation: PSENradar with PNOZmulti 2
Safe radar sensors are ideal where optoelectronic sensors reach their limits: rugged environments, consisting of dust, water and smoke such as outdoors or in material processing. That's because radar technology (FMCW: frequency modulated continuous wave) ensures high availability even where there are external influences such as dust, dirt, rain, light, sparks or vibrations.
The underlying volumetric monitoring with a frequency of 24 - 24.25 GHz can be used up to SIL 2, PL d and Category 3, which is often a requirement in robot applications. The complete solution also has additional interfaces, such as Ethernet and Profisafe, so making it easy to use the safety radar sensor in retrofit applications. The advantages include-
- Resistant to dust, rain, dirt, light, sparks, steam and vibration
- High flexibility
- Series connection upto 6 sensors
- Rear access protection to prevent the machine from starting if there are people in danger zone
- Detection function and restart interlock
