Teaching Optical Fiber Photoelectric Sensor
Sensitivity Easily Adjusted with
Teaching
Four Amplifiers built into Four-channel Fiber
Amplifier Models.
Four Fiber Units can be wired close together and
connected to a Four-channel Fiber Amplifier
without mutual interference.
Compact with a width of 32 mm (Four-channel
Fiber Amplifier Models) and a width of 10 mm
(One-channel Fiber Amplifier Models).
Built-in initial operating level compensation func-
tion allows no-object teaching.

Pink and blue (0 V) wires are
short-circuited when remote input is
ON. (0 V short-circuit current: 1 mA
max.)
Pink and blue (0 V) wires are not
short-circuited when remote input is
OFF. (Open or 9 V min.; max. input
voltage: 24 V)
Response time is 0.5 ms max. when
remote input is OFF.
Blue and pink wires are short-circuited
when remote input is ON.
Blue and pink wires are not
short-circuited when remote input is OFF.

Note:
Light ON and Dark ON switch selectable
It is possible to disable the OFF-delay timer function by using the switch setting.
