The Sensors connected together must satisfy the following conditions:
i

+ (N-1) x i ≤ Upper-limit of control output of each Sensor

L

- N x VR≥ Load operating voltage

S

N = No. of Sensors

S

i = Current consumption of the Sensor
i

= Load current

L

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.

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.

Precautions

Operating Environment

! Caution

Power supply

Do not impose an exessive 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 ex­plode or burn.

Do not use the Sensor in locations with explosive or flamma­ble gas.

Correct Use

Design

Effects of Surrounding Metal

Provide a minimum distance between the Sensor and the sur­rounding metal as shown in the table below.

E2Q4

Be sure to abide by the following precautions for the safe op­eration of the Sensor.

Wiring

Power Supply Voltage and Output Load Power Supply Volt­age

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.

Mutual Interference

If more than one Sensor is located in parallel, ensure to main­tain enough space between adjacent Sensors to suppress
mutual interference as provided in the following diagram.

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.

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 inde­pendent 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 met­al conduit to prevent against Proximity Sensor damage or
malfunction.

Maintenance and Inspection

Periodically perform the following checks to ensure stable op­eration of the Proximity Sensor over a long period of time.

• Check for mounting position, dislocation, looseness or dis­tortion 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 envi­ronmental 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 ambi­ent temperature range and do not use the Proximity Sensor
outdoors so that its reliability and life expectancy can be main­tained. Although the Proximity Sensor is water resistive, a
cover to protect the Proximity Sensor from water or water-sol­uble 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 ni­tric, 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 Snesor, in this case connect the
load to the Proximity Sensor through a Relay
