Photoelectric switches in stable metal
housing. Photoelectric proximity
switches WT 12-2 with stepless adjustable scanning distance and optional
background or foreground suppression
as well as sensitivity adjuster for large
scanning distances. Polarization filter
for WL 12-2 photoelectric proximity
switch.
WS/WE 12-2 through-beam photoelectric switches with test input for
function monitoring.
n
Supply voltage 10 to 30 V.
Insensitive to ambient light due to
pulse modulation.
Complementary switching outputs for
light of dark switching with short-circuit
protection in NPN or PNP models.
Available as through-beam photoelectric switch, photoelectric reflex
switch, photoelectric proximity switch.
Variable connection options on the
back and bottom thanks to rotable
equipment plug.
LED signal strength indicator for soiling
monitoring of the optics and as
alignment help (blinking).
Available with fixed attached cable or
4 pole equipment plug.
Flexible mounting options thanks to
dovetail clamp and longitudinal holes.
