Small sensors are go
May 1st 2008 The new PRK 3b photoelectric
sensors from Leuze are said to be
the world's smallest optoelectronic/
laser sensors, capable of
detecting components measuring
less than 0.1mm.
For standard
applications with a
scanning range up to
400mm, the PRK 3b
series has black-andwhite
performance and
reliable switching
operation. This suits
applications in the
assembly and handling
sectors. In an XL
version it provides
reliable detection of
objects with gaps, boreholes
and grooves. The S version
has been optimised for the
detection of small
components and
structured,
coloured
or shiny
objects.
The new sensor has compact
housing of 32 x 11 x 17mm, faster
and more precise detection, and
an ability to cope with interference
from spurious light sources,
reflective packaging as well as
heavy
soiling.
The build has sealing
properties ensuring
conformity to IP67 and IP
69K for areas where
intensive cleaning cycles are
deployed. Development work
on the new photoelectric
sensor generation focused
on reducing life cycle costs,
achieving lower costs in
terms of procurement,
commissioning and operation. More articles from Leuze Mayser Electronic Limited: |
