applications. Plastic optic fi bers have a standard 2.2mm external diameter and
generally have a cylindrical threaded metal head on the end used for mechanical
mounting. These fi bers are usually 1 and 2 meters in length as reductions in per-
formance become signifi cant with lengths over 5 meters. Plastic optic fi bers can
be shortened using a special fi ber-cutting tool, but, it can only be used a limited
number of times. Cutting the fi ber with a non-sharp or non-perpendicular blade
will reduce operating distance. High temperature, extra-fl exible or high effi ciency
plastic optic fi bers are also available.
Laser Sensors
very small objects or to reach very long operating distances. With reference to
the safety of laser radiation (according to the EN60825-1 European standard)
class 1 requires that the laser device is safe under
reasonable operating conditions and is not dangerous
for people in any situation; while class 2 states that
the eye cannot be protected just by looking away or
blinking, thus precautions must be adopted to avoid
staring into the beam.
IMPORTANT: Always consider safety when installing a laser sensor of any
kind. Make sure that the laser beam cannot inadvertently shine into the eyes of
people passing by or working in the vicinity. See safety information on page 232.
Mounting
Mounting brackets and hardware are included with sensors, where applicable.
Use the hardware for mounting, along with washers and spring washers or lock
nuts. Do not overtighten hardware. Overtightening causes damage to the hous-
ing and will adversely affect the waterproof characteristics of the sensor.
Best results can be obtained when the sensor is mounted so that the object
sensed is in the center of the beam, rather than when the object is located near
the edges of the sensing window. In addition, the most reliable sensing occurs
when the majority of the objects being sensed are well within the sensing range,
rather than at the extreme near and far limits.
Wiring
Avoid running high-voltages or power lines in the same conduit with sensor
signal lines. This prevents inaccurate results or damage from induced noise. Use
a separate conduit when the infl uence of power lines or electromagnetic equip-
ment may occur, particularly when the distance of the wiring is extended.
IMPORTANT: Connect the sensor cables and wires as noted in the individual
Wiring sections. Failure to connect as shown in wiring diagrams will result in
damage to the internal circuit.
Through-beam fi bers
A LASER (Light Amplifi cation by Stimulated Emission of Radiation) is
an electronic device, such as a diode, that converts an energy source
into a very thin and concentrated light beam, suitable for detecting

When extending sensor cables and wires, make sure to use cables equal or
superior to that recommended in the individual specifi cations sections.
When wiring terminals, be sure to prevent contact between adjoining terminals.
When using ring or fork lug terminals, use the insulated sleeve style only. Each
sensor terminal can accept only one ring or fork lug terminal.
Power Supply
Noise resistance characteristics are improved when a sensor is grounded to the
0V power terminal. If the 0V power terminal is not at ground potential, use a
ceramic 0.01μF capacitor which can withstand 250V AC minimum.
Miscellaneous
Strong magnetic fi elds may detract from the accuracy of the sensing measure-
ments. Avoid mounting a sensor directly to machinery, since the housing is con-
nected to the electronic circuit ground of the sensor. If it is necessary to mount a
sensor on machinery, use the insulating plate and sleeve provided.

When using a switching power supply, be sure to ground
the FG terminal to eliminate high-frequency noise. The
power supply should include an insulating transformer, not
an autotransformer.
The compact PS5R-A power supply is the perfect compan-
ion item for most IDEC sensors. This power supply is only
1.77” (45mm) wide, 3.15” (80mm) tall, and 2.76” (70mm)
deep. Call an IDEC representative for more details.
