PHOTOSWITCHR Photoelectric Sensors
42BC Long Range Background Suppression
Description
The 42BC photoelectric sensor offers
high performance background
suppression performance at sensing
ranges up to 2m (6.6ft). This type of
sensing capability is desirable in
applications where standard transmitted
beam or retroreflective sensing is not
practical due to no easy access to both
sides of the target or when economics
is a major factor.
The 42BC photoelectric sensor uses a
triangulation method to mechanically
adjust the sensing angle, thereby,
ensuring reliable detection of the target
while ignoring the background. Using
the sensitivity adjustment on the top
cover, the desired sensing range can
be dialed in to meet the specific
application.
The 42BC is available in either a 1m
(3.3ft) or 2m (6.6ft) sensing range. For
applications where the sensing
distances are much shorter use of the
RightSight background suppression
sensor is recommended. These
sensors offer a fixed 50mm (2in) and
100mm (4in) sensing range. Similar
long range sensing distances may be
solved with the 42BT photoelectric
sensor also. This sensor provides a
smaller package style for space critical
installations.
