Q
General Information
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 influence of power lines or electromagnetic
equipment 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.
When extending sensor cables and wires, make sure to use cables equal or
superior to that recommended in the individual specifications sections.
When wiring terminals, be sure to prevent contact between adjoining termi-
nals. When using ring or fork lug terminals, use the insulated sleeve style
only. Each sensor terminal can accept only one ring of fork lug terminal.
On ISF series photoelectric sensors, use recommended cable, along with the
attached packing gland and washer, when wiring the terminals. This ensures
waterproof and dustproof characteristics.
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.
When using a switching power supply, be sure to ground the FG terminal to
eliminate high-frequency noise. The power supply should include an insulat-
ing transformer, not an autotransformer.
On ISF series photoelectric sensors, the power supply should be sized accord-
ing to the voltage drop through the lead wire when using a long extension for
the DC type (328' or 100m maximum extension).
The compact PS5R-A power supply is the perfect companion 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.
Strong magnetic fields may detract from the accuracy of the sensing measure-
ment. 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.

Attenuation: Reduction of beam intensity as a result of environmental fac-
tors such as dust, humidity, steam, etc.
Dark on: Output energized when light is not detected by the receiving ele-
ment. For through-beam sensors, light from the projector is not detected by
the receiver when an object is present. For reflected light sensors, light is
not detected when it is not reflected from an object surface.
Diffuse-reflected light sensors: Sensors that detect all scattered,
reflected light. Light reflected from nearby surfaces, as well as intended
object surface, is detected. Diffuse-reflected light sensors are often called
“proximity switches,” since they switch when any object is near. Also use
to detect color contrast when colors reflect light intensity differently (green
LED recommended for this application).
EEPROM: Acronym which stands for electronically erasable, programma-
ble, read only memory.
Excess gain: Ratio of optical power available at a given projector-to-
receiver range divided by the minimum optical power required to trigger
the receiver.
Extraneous light: Incident light received by a sensor, irrelated to the pres-
ence or absence of object being detected. Extraneous light is usually
unwanted background light such as sunlight and incandescent lamps in
close proximity.
located on an XYZ axis of light, hue, and chroma values.
Hysteresis: Operating point and release point at different levels. For solid
state sensors, this is accomplished electrically. For mechanical switches, it
results from storing potential energy before the transition occurs.
Light on: Output energized when light is detected by receiving element.
For through-beam sensors, light from the projector is detected by the
receiver when an object is not present. For reflected light sensors, light is
detected when it is reflected from an object surface.
Linearity: Measurement of how nearly linear, that is, how accurate actual
analog output is, with respect to distance.
NPN/PNP: Types of open collector transistors. NPN is a sink transistor;
output on establishes negative potential difference. PNP is a source tran-
sistor; output on establishes positive potential difference.
Polarizing: Filtering out all reflected light except that which is projected in
one plane only. Polarized retro-reflected light sensors detect the light from
corner-cube type reflectors when an object is not present.
Reflected-light sensors: Sensors with the projector and receiver in one
housing. Light is projected by the light source, and reflected light is
received by the optical surface. Includes diffuse-reflected, retro-reflected,
limited-reflected, and spot-reflected sensors.
Repeatability: Ability of a sensor to reproduce output readings consis-
tently when the same value is applied consecutively, in the same direction,
for a specified number of cycles, or for a specified time duration.
Resolution: Overall dimension of the smallest object which can be
detected (when sensing the presence of an object) or smallest increment of
distance which can be distinguished with reliable results (when sensing
the position of an object).
Response time: Time elapsed between input and output. Total response
time is the sum of object detection, amplifier response, and output
response times.
Retro-reflective scan: This type of reflected light sensor uses a special
reflector to return projected light when an object is not present. Sensor
detects the presence of an object when the light is reflected differently.
Through-beam sensors: Sensors with a separate projector and receiver.
The light source from the projector is detected by the receiver, except when
an object is present.
Transient: Undesirable surge of current (many times larger than normal
current) for a very short period, such as during the start-up of an inductive
motor.
E: The measurement of color difference as a three-variable function,
