Capacitive proximity sensors CM PTFE

Category Tag
  • Lower maintenance costs due to a durable PTFE housing that withstands harsh ambient conditions
  • Quick and easy adjustment via potentiometer saves installation and setup time
  • Straightforward and safe sensor technology as an alternative to photoelectric and inductive sensors in applications such as detecting a product in a sealed box, container, or tank
  • High electromagnetic compatibility prevents incorrect switching, thus increasing machine availability
  • High shock and vibration resistance increases sensor life and reduces machine maintenance costs


Capacitive proximity sensors can detect all types of material: powder-based, granulated, liquid, and solid.

The CM18 PTFE is ideal for detecting the level of acids, alkalis, or solvents, for example. It is also used for detection in aggressive environments (acid fumes). PTFE-housing is resistant to almost all chemicals and organic solvents.
