Wiring diagram
Functional principle
Inductive sensors detect metal objects contactless
and wear-free. Due to the patented multi-coil
system, uprox®+ sensors have distinct advantages
over conventional sensors. They excel in largest
switching distances, maximum flexibility
and operational reliability as well as efficient
standardization.

All non-flush mountable uprox®+ threaded barrel
sensors can be screwed to the upper edge of the
barrel. Thus safe operation is guaranteed with a
reduced switching distance of max. 20 %.
When installed in an aperture plate a distance of X
= 70 mm must be observed.
