W 260 Photoelectric switches
W 260: Standard photoelectric
switch series for a broad range
of applications
The W 260 series with its
impressive scanning ranges and
features has been specially
designed for a wide variety of
different applications. The
sensors, through-beam photo-
electric switches, energetic
photoelectric proximity switches,
and photoelectric reflex switches
with background suppression are
contained in robust plastic
housings. Handling is simple and
user-friendly. Two supply voltages
are available:
■low voltage 10 . ..30 V DC with
PNP or NPN transistor switching
output and test input and
■universal voltage 12 . . . 24 V DC
and 24 . . . 240 V AC with poten-
tial-free relay contact (SPDT) or,
alternatively, adjustable time
delay.
A variety of features make these
sensors particularly operator-
friendly. These include visible red
transmitted light used as an align-
ment aid, or the simple and
flexible connection system,
glass/stainless steel fibre-optic
cables for harsh operating condi-
tions in confined environments.
All of these benefits open up
applications far beyond hand-
ling/warehousing systems, the
packaging industry and wood
working. All device variants
have been granted UL and CSA
approval.
One last highlight: the W 260
complies with EN 50081-1
(interference radiation). This
makes it the perfect sensor
solution for door and gate control
systems in underground garages
and for use in residential blocks
or hotels.
