"Acids, bases and solvents frequently attack sensors in normal plastic housing. But these chemicals have no chance against the new SICK CM 18 PTFE capacitive proximity sensors, making them particularly suitable for detecting acids, bases and solvents," says Patrick Pitts, marketing manager of Rhomberg, which imports the sensors.
PTFE (polytetrafluorethyelene) is resistant against almost all chemicals and organics solvents. As a result the material is ideal for sensors that are exposed to aggressive media and fumes that they give off.
Using PTFE for the housing and the M18 screws allows the sensor to be used for checking the filling levels of aggressive media, eg, hydrochloric acid, a variety of alkalis and numerous solvents. The same is true of object detection in environments in which these materials may occur. The material is also suitable wherever plants require frequent cleaning with chemicals or at high temperatures. As PTFE does not absorb any liquid it is not possible for any build-up of the medium to take place on active switching surfaces - preventing spurious signals while checking filling levels or presence.
The use of PTFE has no effect on functional features of the CM 18. Like the plastic version, the advantages of the CM 18 PTFE include an enclosure rating of IP67, high electro-magnetic compatibility (EMC) - complying with device standard EN 60947-5-2, a long switching distance that can be continuously adjusted between 3 mm and 8mm, PNP or NPN switching output, antivalent output functions and a 2 m connecting cable.
