Magnetic proximity sensors MM

Category Tag
  • Non-contact operation eliminates interference from dirt, dust and vibrations, increasing sensor life and reducing maintenance costs
  • Space-saving installation due to small design
  • Large operating ranges with reliable switching increase throughput
  • Non-contact, universal detection through several substances, including plastic containers and pipes protective PTFE walls and non-magnetic metal walls


MM magnetic proximity sensors provide long sensing ranges that can reliably detect magnetic objects. Magnetic proximity sensors are resistant to dust, heat, vibrations and other harsh environments. The MM magnetic sensors are enclosed in a cylindrical housing and are available in sizes MM08, MM12 and MM18.
