Compact Photoelectric Sensor CX-400 SERIES
Notes: 1) Where measurement conditions have not been specied precisely, the conditions used were an
ambient temperature of +23 °C +73.4 °F.
2) The adjustable range stands for the maximum sensing range which can be set with the distance
adjuster. The sensor can detect an object 2 mm 0.079 in [CX-444(-P): 15 mm 0.591 in, CX-442(-P):
20 mm 0.787 in], or more, away.
3) Note that detection may be unstable depending on the mounting conditions or the sensing
object. In the state that this product is mounted, be sure to check the operation with the actual
sensing object.
