多功能传感器

the photoelectric sensors of the s2 series are enclosed in sturdy plastic housings,
developed to guarantee the complete protection of the control panel and
connection terminals. 
the free voltage versions present a relay output, while the 10-30 vdc versions
have a double npn and pnpoutput, both available with 1 or 2 m proximity, 5 m
polarised retroreflex, 3 m polarised retroreflex  and 10 or 50 m through beam optic
functions.
the red output led and the green stability led are visible through the ip66
hermetically-sealed cover, that also protects the terminal block and commands,
such as the sensitivity adjustment trimmer and dark/light operating mode se-lector.
the versions with output timing present a trimmer to regulate the time up to 16 s.
and a se-lector to set 5 different functions.
