Introducing transparent object sensing type sensor
CX-48
Our unique optical system and transparent object sensing
circuit provide stable sensing of thinner transparent objects
than the conventional models.
Twice the
sensing
range!

Reflector setting range CX-481: 300 to 500 mm 11.811 to 19.685 in
CX-482: 1 to 2 m 3.281 to 6.562 ft
CX-483: 500 to 1,000 mm 19.685 to 39.370 in
[with the RF-230 reflector at the optimum condition (Note)]
Each object should pass across the beam at the center between the sensor and the reflector.
 : Length of cylindrical glasses
t : Thickness of sensing object
Note:
The optimum condition is defined as the condition in which the sensitivity level
is set such that the stability indicator just lights up when the object is absent.

Beam axis alignment made easy with a high luminance spot beam
CX-423
These sensors have a high luminance
red LED spot beam which provides bright
visibility enabling the sensing position to
be checked at a glance.
Because it achieved small beam spot

accurately detected.
Reduction of volume adjustment labor
All models
Because these sensors possess many
variations depending on the sensing
range, they enable you to make optimal
volume adjustment easily.
