Capacitive sensors are used in machine systems and equipment for no-contact
motion surveillance. They consist of two coaxial electrodes, a condenser and RC
generator. This type of sensors reacts to both metal and non-metal objects, as
the gearing distance for non-metal objects depends on their dielectric
constants. They allow gearing distance adjustment for non-magnetic conductive
materials. They are developed on the base of PNP and NPN transition. They have
small dimensions and feature a metal cylindrical shell resistant to vibrations
and a plastic lid which is oil and water resistant. Technical characteristics: -
