Ultrasonic proximity switches approved for use in hazardous areas

1st April 2013


Siemens Automation and Drives (A&D) has developed a new range of ultrasonic proximity switches for use in hazardous (Ex) areas. The contact-free Simatic PXS810 sensors are available in M18 compact design and in M30K3 format with a fixed sensor head.

The M18 types are designed for sensing ranges 5 to 30 and 15 to 100cm, and the M30 K3 for 6 to 30cm and a maximum of 60 to 600cm. The sensors can each be operated as diffuse sensors, retro-reflective sensors or thru-beam sensors and are suitable for use in areas such as paint shops, woodworking and food processing.

The SimaticPXS810 proximity switches are additionally equipped with stainless steel housings and Teflon coatings especially for use in the food and beverage industries. Stainless steel and Teflon protect the sensor against abrasive detergents. The new sensors meet Atex safety requirements in accordance with RL94/9/EG for Zone2 (gas) and Zone22 (dust).
