Product Description
A family of inductive prox-
imity switches in industrial
standard nickel-plated brass
housings. They are charac-
terized by extremely high
performance in a very small
design, to satisfy the most
demanding
applications,
also where the space avail-
able for the sensor is limited
and extended sensing range
is requested.
Output is open collector
NPN or PNP transistors.
