R
Extended Range Inductive Prox
E2EM
Greater Sensing Distance Offers
Greater Design Flexibility
H Sensing distances approximately 1.5 to
2 times larger than that of any
conventional Sensor
H Reduces problems such as the collision
of workpieces
H The E2EM has no polarity, thus
eliminating problems associated with
reversed wiring

Precautions
J SAFETY PRECAUTIONS
Power Supply
Effects of Surrounding Metal
When mounting the E2EM within a metal panel, ensure that the
clearances given in the following table are maintained.
Do not impose an excessive voltage on the E2EM, otherwise it
may be damaged. Do not impose AC current (100 VAC) on any
E2EM DC model, otherwise it may be damaged.
ℓ
Load Short-circuit
Do not short-circuit the load, or the E2EM may be damaged.
The E2EM’s short-circuit protection function will be valid if the
polarity of the supply voltage imposed is correct and within the
rated voltage range.

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 before supplying power to the load.
Note: To convert mm to inches, multiply mm’s by 0.03937.
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.
AND/OR Connection
When using the product in an AND/OR circuit, the product may
not function properly due to incorrect pulses or leakage currents.
Therefore, confirm that no problems will occur before actually
using the product in such a circuit.

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.
Wiring through Metal Conduit:
(Unit: mm) See note.
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 prevent against Proximity Sensor damage or
malfunctioning.

Cable length must be less than 200 m (656 ft.).
The tractive force is 50 N (11.24 lbF).

Connection conditions are determined from the relationship
between the input ON voltage and OFF voltage of the PC and the
output residual voltage and leakage current of the Proximity
Sensor.

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.
Connection is possible under the following conditions.
Example values on the PC side
ON voltage: 10.2 V min.
Do not tighten the nut with excessive force. A washer must be
used with the nut.
OFF voltage: 3 V max.
Input impedance: 3.5 kΩ
Example values on the Proximity Sensor side
Output residual voltage: 5 V max.
Leakage current: 0.8 mA max.

Countermeasures Against Leakage Current
J MAINTENANCE AND INSPECTION
Periodically perform the following checks to ensure stable
operation of the Proximity Sensor over a long period of time.
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.
1. Check for mounting position, dislocation, looseness, or
distortion of the Proximity Sensor and sensing objects.
Load
2. Check for loose wiring and connections, improper contacts,
V
S
and line breakage.
Bleeder resistor R
3. Check for attachment or accumulation of metal powder or
dust.
4. Check for abnormal temperature conditions and other
environmental conditions.
5. Check for proper lighting of indicators (for models with a set
indicator.)
Refer to the following to calculate the bleeder resistance and the
allowable power of the bleeder resistor.
Leakage Current
Never disassemble or repair the Sensor.
When the Proximity Sensor is OFF, the Proximity Sensor has
leakage current. 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.
J ENVIRONMENT
Water Resistance
Do not use the Proximity Sensor underwater, outdoors, or in the

P > V /R (mW)

Operating Environment
P: The allowable power of the bleeder resistor. (The actual
power capacity of the bleeder resistor must be at least a few
times larger than the allowable power of the bleeder resistor.)
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.
i : Leakage current of the Proximity Sensor (mA)
R

: Load reset current (mA)
OFF
It is recommended that 15 kΩ max./450 mW min. for 12 VDC and
30 kΩ max./0.1 W min. for 24 VDC be used.
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 Sensor, in which case connect the load to
the Proximity Sensor through a relay.
J CONNECTING LOAD TO DC 2-WIRE
SENSOR
Refer to the following before using DC 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
suppressor to the machine.
