Photomicrosensors Technical Guide
Design Considerations
Precautions for Photomicrosensors with Modulated Light
When using Photomicrosensors with Modulated Light (models that
begin with EE-SP), the design must take into account the effects of
power source and cable length. Photomicrosensors with Modulated
Light are more easily affected than Photomicrosensors with Non-
modulated Light (models that begin with EE-SX or EE-SY).
Photomicrosensors with Modulated Light that are easily affected:
EE-SPX301/401, EE-SPY30@/40@,
E-SPZ301@/401@, EE-SPY31@/41@,
EE-SPX303/403, EE-SPW311/411,
EE-SPX74@/84@, EE-SPX@@@-W
Photomicrosensors with Modulated Light that are not easily
affected:
EE-SPX613, EE-SPY801/802
Reasons for Interference from Power and Cable Length on
Photomicrosensors with Modulated Light
As explained in Principles, an LED emitter is pulse-lighted to produce
modulated light. A large current momentarily flows to the
Photomicrosensor in sync with this pulse timing. This causes a
pulsating consumption current.
A photoelectric sensor incorporates a capacitor with sufficient
capacity, and is virtually unaffected by the pulse of the consumption
current. With a small Photomicrosensor, however, it is difficult to have
a capacitor with a sufficient capacity. Accordingly, when the cable
length is long or depending on the type of power source, it may
become impossible to keep up with the pulse of the consumption
current and operation may become unstable.
Countermeasures
<Adding a Capacitor>
Attach a capacitor of 10 μF min. (e.g., a film capacitor) to the wires
as close as possible to the Sensor. (Use a capacitor with a
dielectric strength that is at least twice the Sensor's power supply
voltage. Do not use tantalum capacitors. A short-circuit may cause
the capacitor to ignite due to the large current flow.)

<Cable Length>
Design the configuration so that the maximum total cable length for
the Photomicrosensor with Modulated Light is 2 m.
When using a cable longer than 2 m, attach a capacitor (e.g., an
aluminum electrolytic capacitor) with a capacity of approximately
10 μF to the wires as shown below. The distance between the
terminal and the capacitor must be within 2 m. Make sure that the
total cable length is no longer than 5 m. To use a cable length longer
than 5 m, use a PLC or other means to read the sensor output and
then transmit the signals using a PLC's communications. Although
cables are capable of being extended longer than 5 m, performance
is likely to be affected by noise interference from adjacent cables and
other devices. Voltage drops due to the resistance of the cable
material itself will also influence performance. Therefore, factors,
such as the difference in voltage between the end of the cable and
the sensor and noise levels, must be given full consideration.

Extension cable
Note: The length that cables can be extended depends on the
Photomicrosensor model and cable specifications. Refer to the specific
precautions for each Photomicrosensor being used before extending
cables. The Photomicrosensors with Non-modulated Light (models that
begin with EE-SX or EE-SY) are not easily affected by the cable length.
(Effective extensions from 20 to 50 m are possible.)
