CAUTIONS
1. Environmental conditions
• Amplifier unit
1) The ambient temperature shall be
kept within a range of –25°C to +55°C
–13°F to 131°F.
2) The operational voltage shall be kept
within a range from 9.6 V to 30 V DC
(including ripple P-P).
3) Use a surge absorber as the internal
circuit may be damaged if external
surge voltages exceed 500 V
[±(1.2T50) µs single polarity full-wave
voltage].
4) Use a load relay with a rated operat-
ing voltage of 12 V DC or 24 V DC. The
voltage applied to the load relay is the
operating voltage of the photoelectric
sensor minus the internal voltage drop
(max. 1.2 V). Voltage fluctuation should
be taken into account.
• Fiber unit
1) The ambient illuminance shall be
3,000 lux or less at the receiver under
an incandescent lamp, and 10,000 lux
or less at the receiver under sunlight.
2) The unit shall not be used at the site
where much steam, dust or corrosive
gas is suspended, water or oil splashes
directly over the unit, or organic solvent
adheres to the unit.
2. Wiring
• Amplifier unit
1) Check all wiring before applying
power since incorrect wiring may dam-
age the internal circuit.
2) Keep in mind that the output area is
broken if a load of 100 mA or more is
connected.
3) Keep in mind that the induction nois-
es cause malfunction and breakage if
the wiring to the photoelectric sensor
runs with the high voltage cables and
the power cable.
4) When crimping the terminals, use
the following tool made by Molex.
Here, the terminal is 5005 TL made by
Molex and the receptacle is 5025-
03R1.
5) When extending the cable, use a
cable of 0.3 mm2(.0005 in2) or more
and limit its length within 100 m 328 ft.
6) When connecting the receptacle to
the plug of the photoelectric sensor,
properly connect them and securely
push in the plug as far as the lock
mechanism is activated. The construc-
tion to prevent reverse connection is
provided.
To remove the receptacle, release the
lock mechanism and pull out the plug
with the receptacle held by hand.
7) It is recommended to attach an auxil-
iary dust protective cover to the recep-
tacle.
8) When the commercially available
switching regulator is used, ground FG
(frame ground terminal) and G (ground
terminal). Otherwise, the switching
noise of power supply may sometimes
cause malfunction. In this case, care
shall be taken.
3. Handling of the fiber unit
1) The fiber unit shall be securely
equipped on the amplifier.
2) Do not tighten with an excessive
strength. Apply a torque of 8 N·m{78.4
kgf·cm 68.048 lbf·in} or less tightening.
3) Do not apply a pulling force of 3 kg
or more to the fiber unit.
4) Make the bending curvature of the
fiber as large as possible. If the curva-
ture is small, the transmission factor is
reduced. So, check this during actual
operation. (The curvature shall be R25
mm or more).
5) Largely bend the fiber and do not
bent it at the root.
6) Do not compress the fiber or apply a
load to it.
