PHOTOSWITCHR Photoelectric Sensors
1–239
Description
The
42KC family of photoelectric sensor
of
fers high performance sensing
capability in a compact rectangular
package. Like the 42KB family
, the
42KC is intended for use in applications
where small size is the key criteria.
Two basic package styles are offered—
end view and side view
. As seen in the
illustrations above, the placement of the
sensor optics determines the view
. End
view sensors have the optics and cable
located at opposite ends while side
view sensors are located on adjacent
sides.
Three basic sensing modes are
available to cover to cover common
applications. A single-turn sensitivity
adjustment is provided on each sensor
for setting the sensor during the
installation phase.
