Wiring diagram
Functional principle
Inductive sensors detect metal objects contactless
and wear-free. uprox® Factor 1 sensors have
significant advantages due to their patented
ferrite-coreless multicoil system. They detect all
metals at the same large switching distance and
are resistant to magnetic fields.
