D-74 Inductive Sensors
Connection
DC type
AC type
Connection type Method Description
AND
(serial connection)
The Sensors connected together must satisfy the following conditions:
iL+ (N-1) x i ≤Upper-limit of control output of each Sensor
VS- N x VR≥Load operating voltage
N = No. of Sensors
VR= Residual voltage of each Sensor
VS= Supply voltage
i = Current consumption of the Sensor
iL= Load current
If the MY Relay, which operate at 24 VDC, is used as a load for example,
a maximum of two Proximity Sensors can be connected to the load.
OR
(parallel connec-
tion)
A minimum of three Sensors with current outputs can be connected in
parallel. The number of Sensors connected in parallel varies with the
Proximity Sensor model.
Connection type Method Description
AND
(serial connection)
If 100 or 200 VAC is imposed on the Proximity Sensors, VL(i.e., the volt-
age imposed on the load) will be obtained from the following.
VL=VS- (residual voltage x no. of Proximity Sensors) (V)
Therefore, if VLis lower than the load operating voltage, the load will not
operate.
A maximum of three Proximity Sensors can be connected in series pro-
vided that the supply voltage is 100 V minimum.
OR
(parallel connec-
tion)
In principle, more than two Proximity Sensors cannot be connected in
parallel.
Provided that Proximity Sensor A does not operate with Proximity Sen-
sor B simultaneously and there is no need to keep the load operating
continuously, the Proximity Sensors can be connected in parallel. In this
case, however, due to the total leakage current of the Proximity Sensors,
the load may not reset properly.
It is not possible to keep the load operating continuously with Proximity
Sensors A and B in simultaneous operation to sense sensing objects due
to the following reason.
When Proximity Sensor A is ON, the voltage imposed on Proximity Sen-
sor A will drop to approximately 10 V and the load current flows into Prox-
imity Sensor A, and when one of the sensing objects is close to Proximity
Sensor B, Proximity Sensor B will not operate because the voltage im-
posed on Proximity Sensor B is 10 V, which is too low.
When Proximity Sensor A is OFF, the voltage imposed on Proximity Sen-
sor B will reach the supply voltage and Proximity Sensor B will be ON.
Then, Proximity Sensor A as well as Proximity Sensor B will be OFF for
approximately 10 ms, which resets the load for an instant. To prevent the
instantaneous resetting of the load, use a relay as shown on the left.

Precautions
Power supply
Do not impose an excessive voltage on the E2Q2, otherwise
it may explode or burn.
Do not connect an AC power supply to any DC model. If AC
power (100 VAC or more) is supplied to the sensor, it may ex-
plode or burn.
Do not connect the AC types without load to the power supply.
The sensor will be damaged.
Be sure to abide by the following precautions for the safe op-
eration of the Sensor.
Wiring
Power Supply Voltage and Output Load Power Supply Volt-
age
Make sure that the power supply to the Sensor is within the
rated voltage range. If a voltage exceeding the rated voltage
range is supplied to the Sensor, it may explode or burn.
Load Short-circuiting
Do not short-circuit the load, otherwise the Sensor may be
damaged.
Connection without Load
Do not connect the power supply to the Sensor with no load
connected, otherwise the internal elements may explode or
burn.
Operating Environment
Do not use the Sensor in locations with explosive or flamma-
ble gas.
Design
Effects of Surrounding Metal
Provide a minimum distance between the Sensor and the sur-
rounding metal as shown in the table below.
Mutual Interference
If more than one Sensor is located in parallel, ensure to main-
tain enough space between adjacent Sensors to suppress
mutual interference as provided in the following diagram.
Power Reset Time
The Sensor is ready to operate within 300 ms after the Sensor
is turned ON. If the load and Sensor are connected to inde-
pendent power supplies respectively, be sure to turn ON the
Sensor before supplying power to the load.
Power OFF
The Proximity Sensor may output a pulse signal when it is
turned OFF. Therefore, it is recommended that the load be
turned OFF before turning OFF the Proximity Sensor.
Power Supply Transformer
When using a DC power supply, make sure that the DC power
supply has an insulated transformer. Do not use a DC power
supply with an auto-transformer.
Sensing Object
The sensing distance of the Proximity Sensor vary with the
metal coating on sensing objects.

Wiring
High-tension cables
Wiring through Metal Conduit:
If there is power or high-tension line near the cable of the
Proximity Sensor, wire the cable through an independent met-
al conduit to prevent against Proximity Sensor damage or
malfunction.
Mounting
Mounting the Sensor
The Proximity Sensor must be subjected to excessive shock
with a hammer when it is installed, otherwise the Proximity
Sensor may be damaged or lose its water-resistivity.
Maintenance and Inspection
Periodically perform the following checks to ensure stable op-
eration of the Proximity Sensor over a long period of time.
• Check for mounting position, dislocation, looseness or dis-
tortion of the Proximity Sensor and sensing objects.
• Check for loose wiring and connections, improper contacts
and line breakage.
• Check for attachment or accumulation of metal powder or
dust.
• Check for abnormal temperature conditions and other envi-
ronmental conditions.
Never disassemble or repair the Sensor.
Environment
Water Resistivity
Do not use the Proximity Sensor underwater, outdoors or in
the rain.
Operating Environment
Be sure to use the Proximity Sensor within its operating ambi-
ent temperature range and do not use the Proximity Sensor
outdoors so that its reliability and life expectancy can be main-
tained. Although the Proximity Sensor is water resistive, a
cover to protect the Proximity Sensor from water or water-sol-
uble machining oil is recommended so that its reliability and
life expectancy can be maintained.
Do not use the Proximity Sensor in an environment with
chemical gas (e.g., strong alkaline or acid gasses including ni-
tric, chromic and concentrated sulfuric acid gases).
Inrush Current
A load that has a large inrush current (e.g., a lamp or motor)
will damage the Proximity Sensor, in this case connect the
load to the Proximity Sensor through a Relay
In the interest of product improvement, specifications are subject to change without notice.
