Precautions
Mounting
Do not tighten the nut with excessive force. A washer must be
used with the nut.
Note: The table below shows the tightening torques for part A and
part B nuts. In the previous examples, the nut is on the sensor
head side (part B) and hence the tightening torque for part B
applies. If this nut is in part A, the tightening torque for part A
applies instead.
Refer to the following to mount the E2E-CR8 and E2E-C1
non-screw models.
Tighten the screw to a torque of 0.2 N·m maximum to secure
the E2E-CR8 and a torque of 0.4 N·m maximum to secure the
E2E-C1.
Effects of Surrounding Metal
When mounting the E2E within a metal panel, ensure that the
clearances given in the following table are maintained. Failure
to maintain these distances may cause deterioration in the
performance of the sensor.
Mutual Interference
When installing two or more Sensors face to face or side by
side, ensure that the minimum distances given in the following
table are maintained.
Note: Values in parentheses apply to Sensors operating at different frequen-
cies.

Precautions for Safe Use
The colors in parentheses are previous wire colors.
Precautions for Correct Use
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 Proximity Sensor and
load respectively, be sure to supply power to the Proximity Sensor be-
fore supplying power to the load.
Power OFF
The Proximity Sensor may output a pulse signal when it is turned
OFF. Therefore, it is recommended to turn OFF the load before turn-
ing 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
Metal Coating:
The sensing distances of the Proximity Sensor vary with the metal
coating on sensing objects.
Wiring
High-tension Lines
Wiring through Metal Conduit
If there is a power or high-tension line near the cable of the Proximity
Sensor, wire the cable through an independent metal conduit to pre-
vent against Proximity Sensor damage or malfunctioning.
Cable Tractive Force
Do not pull on cables with tractive forces exceeding the following.
Mounting
The Proximity Sensor must not be subjected to excessive shock with
a hammer when it is installed, otherwise the Proximity Sensor may be
damaged or lose its water-resistivity.
Environment
Water Resistivity
Do not use the Proximity Sensor underwater, outdoors, or in the rain.
WARNING
This product is not designed or rated for ensuring safety
of persons.
Do not use it for such purposes.
Item Examples
Power supply
Do not impose an excessive voltage on the
E2E, otherwise it may explode or burn. Do
not impose 100 VAC on any E2E DC Model,
otherwise it may explode or burn.
Load short-circuit
Do not short-circuit the load, or the E2E may
explode or burn.
The E2E’s short-circuit protection function is
valid if the polarity of the supply voltage
imposed is correct and within the rated
voltage range.
Wiring
Be sure to wire the E2E and load correctly,
otherwise it may explode or burn.
Connection with no load
Make sure to connect a proper load to the
E2E in operation, otherwise it may explode or
burn.

6Inductive Sensors
Operating Environment
Be sure to use the Proximity Sensor within its operating ambient tem-
perature 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 con-
centrated sulfuric acid gases).
Connection to a PLC
Required Conditions
Connection to a PLC is possible if the specifications of the PLC and
the Proximity Sensor satisfy the following conditions. (The meanings
of the symbols are given below.)
1. The ON voltage of the PLC and the residual voltage of the Prox-
imity Sensor must satisfy the following.
VON VCC – VR
2. The OFF current of the PLC and the leakage current of the Prox-
imity Sensor must satisfy the following.
IOFF Ileak
(If the OFF current is not listed in the specifications, take it to be
1.3 mA.)
3. The ON current of the PLC and the control output (IOUT) of the
Proximity Sensor must satisfy the following.
IOUT(min) ION IOUT(max)
The ON current of the PLC will vary, however, with the power sup-
ply voltage and the input impedance used as shown in the follow-
ing equation.
ION = (VCC – VR– )/RIN
Example
In this example, the above conditions are checked for when the PLC
model is the C200H-ID212, the Proximity Sensor model is the E2E-
X7D1-N, and the power supply voltage is 24 V.
1. VON (14.4 V) VCC (20.4 V) – VR(3 V) = 17.4 V: OK
2. IOFF (1.3 mA) Ileak (0.8 mA): OK
3. ION = [VCC (20.4 V) – VR(3 V) –
4.5 mA
Therefore,
IOUT(min) (3 mA) ION (4.5 mA): OK
VON: ON voltage of PLC (14.4 V)
ION: ON current of PLC (typ. 7 mA)
IOFF: OFF current of PLC (1.3 mA)
RIN: Input impedance of PLC (3 k)
VR: Output residual voltage of Proximity Sensor (3 V)
Ileak: Leakage current of Proximity Sensor (0.8 mA)
IOUT: Control output of Proximity Sensor (3 to 100 mA)
VCC: Power supply voltage (PLC: 20.4 to 26.4 V)
Values in parentheses are for the following PLC model and Proximity
Sensor model.
PLC: C200H-ID212
Proximity Sensor: E2E-X7D1-N
Note: please refer to complete E2E/E2E2 datasheet for details on E2E-X7D1-N
VPC
VPC (4 V)]/RIN (3 k)
VPC: Internal residual voltage of PLC (4 V)
Model Connection type Method Description
DC 3-wire 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 operates at 24 VDC, is used
as a load for example, a maximum of two Proximity
Sensors can be connected to the load.
