New W 190L series of laser photoelectric switches
Specialists for standard
and special applications
Externally uniform, but internally with differing laser technology adapted
for meeting application requirements – this is the new W 190L. The
Standard series of this sensor family is designed for “uncritical” applications.
The W 190L High Grade series is intended for demanding applications
and provides maximum accuracy and resolution.
The W 190L series consists of Standard and High-grade laser sensors for demanding
applications
Numerous features in common
As distinctive as the interiors of the individual W 190L sensors can be, they
are all similar on the outside. All sensors have a red-light laser in Protection
Class 2. As a result, the sensors can be rapidly and accurately aligned on target
objects. The rotatable M8 plug or the 2 m cable are just as much device
standards as the yellow and green LED display, providing practical assistance
during commissioning and operation. The uniform compact plastic housing
made of ABS allows use of the devices even under difficult conditions.

For standard use
The W 190L Standard series is a complete
family of photoelectric switches
consisting of through-beam and reflex
photoelectric switches as well as proximity
switches with adjustable background
suppression. They are reliable,
user-friendly and economical sensors,
whose basic features and functions are
designed for solving conventional applications.
High Grade: individually optimised
for demanding applications
Specialisation is trumps with the
W 190 Laser High Grade series. Thus,
the CMOS technology of the WTB 190TL
scanner offers a very high resolution.
This permits reliable detection of objects
with highly reflective surfaces,
such as foils. With appropriate programming,
the scanner can operate
with a choice of background or foreground
suppression. The WLG 190T
glass photoelectric switch is designed
for the reliable detection of transparent
objects. Whether glass bottles or flat
objects, such as discs; whether thinwalled
PET plastics or transparent foils
– the WLG 190T makes even the almost
invisible visible. Both sensors offer
teach-in programming at the touch
of a button or externally via the control
cable. This allows simple definition of
scanning distances and ranges. Menu
navigation takes place on an easily visible
numerical display via which, for example,
the type of switching can be
programmed and, if necessary, a time
delay activated.
