Precautions
J INSTALLATION
Power Reset Time
The Proximity Sensor is ready to operate within 100 ms after
power is supplied. If power supplies are connected to the Proxim-
ity Sensor and load respectively, be sure to supply power to the
Proximity Sensor before supplying power to the load.
Power OFF
The Proximity Sensor may output a pulse signal when it is turned
off. Turn off the load 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.
Target Object
Metal Coating
The sensing distances of the Proximity Sensor vary with the met-
al coating on target objects.
J WIRING
High-tension Lines
Wiring through Metal Conduit
If there is a power or high-tension line near the cable of the Prox-
imity Sensor, wire the cable through an independent metal con-
duit to prevent against Proximity Sensor damage or malfunction-
ing.
Cable Tractive Force
Do not pull cables with the tractive forces exceeding the follow-
ing.
J MOUNTING
The Proximity Sensor must not be subjected to excessive shock
with a hammer when it is installed, or the Proximity Sensor may
be damaged or lose its water-resistance.
J ENVIRONMENT
Water Resistance
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. Al-
though the Proximity Sensor is water resistant, 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).
J CONNECTING LOAD
Refer to the following before using AC 2-wire Proximity Sensors.
Surge Protection
Although the Proximity Sensor has a surge absorption circuit, if
there is any machine that has a large surge current (e.g., a motor

or welding machine) near the Proximity Sensor, connect a surge
absorber to the machine.
Leakage Current
When the Proximity Sensor is OFF, the Proximity Sensor has
leakage current. Refer to Leakage Current Characteristics. In this
case, the load is imposed with a small voltage and the load may
not be reset. Before using the Proximity Sensor, make sure that
this voltage is less than the load reset voltage. The AC 2-wire
Proximity Sensor cannot be connected to any card-lift-off relay
(e.g., the G2A) because contact vibration of the relay will be
caused by the leakage current and the life of the relay will be
shortened.
Countermeasures Against Leakage Current
AC 2-wire Models
Connect a bleeder resistor as the bypass for the leakage current
so that the current flowing into the load will be less than the load
reset current.
As shown in the following diagram, connect the bleeder resistor
so that the current flowing into the Proximity Sensor will be 10
mA minimum and the residual voltage imposed on the load will
be less than the load reset voltage.
Refer to the following to calculate the bleeder resistance and the
allowable power of the bleeder resistor.
R ≦ V
P > V
P: The allowable power of the bleeder resistor. (The actual pow-
I:
The following resistors are recommended.
100 VAC (supply voltage): A resistor with a resistance of 10 kΩ
maximum and an allowable power of 3 W minimum
200 VAC (supply voltage): A resistor with a resistance of 20 kΩ
maximum and an allowable power of 10 W minimum
If these resistors generate excessive heat, use a resistor with a
resistance of 10 kΩ maximum and an allowable power of 5 W
minimum at 100 VAC and a resistor with a resistance of 20 kΩ
maximum and an allowable power of 10 W minimum at 200 VAC
instead.
er capacity of the bleeder resistor must be at least a few
times as large as the allowable power of the bleeder resistor.)
