NAMUR magnetic proximity sensors in a cylindrical housing for explosive areas

Your Benefits

  • NAMUR version ensures safe function in explosion-hazardous areas
  • Non-contact operation eliminates interference from dirt, dust and vibrations, increasing sensor life and reducing maintenance costs
  • Large sensing ranges ensure reliable switching, even with target position tolerances
  • Universal use since detection through other objects, such as plastic walls or non-magnetic stainless steel walls, is also possible

Overview

NAMUR magnetic proximity sensors in a cylindrical housing for explosive areas

MM NAMUR magnetic proximity sensors provide large operating distances that can reliably detect magnetic objects. Magnetic proximity sensors are resistant to dust, heat and vibration, making them ideal for use in harsh environments – even highly explosive atmospheres. By using magnetic conductors, these sensors are able to reliably detect objects over greater distances. The NAMUR design for hazardous areas is available in MM12 and MM18 designs.
