Precautions
●
For adjustment
• The passage point of the detection object should be the
central point between the reflective plate and the photoelec-
tric switch. If too close to the reflective plate, an error may
result.
• To obtain sufficient detection performance, the E39-R1
must be used for the reflective plate unless otherwise spec-
ified.
