DC 3-wire Models / DC 4-wire (NO+NC)
Note 1. The response frequency is an average value. Measurement conditions are as follows: standard target, a distance of twice the standard
target distance between targets, and a setting distance of half the sensing distance.
2. When using any model at an ambient temperature between −40°C and −25°C and a power voltage between 30 and 32 VDC, use a load
current of 100 mA max.,
3. For USA and Canada: use class 2 circuit only.
4. -B3/ -C3 NO+NC models are available in M12, M18 and M30 housings with M12 connectors, pre-wired and with cable end connectors.

Precautions
Safety Precautions
Power Supply
Do not impose an excessive voltage on the E2A, otherwise it may be
damaged. Do not impose AC current (100 to 240 VAC) on any DC
model, otherwise it may be damaged.
Load Short-circuit
Do not short-circuit the load, or the E2A may be damaged.
The E2A’s shor t-circuit protection function will be valid if the polar ity
of the supply voltage imposed is correct and within the rated voltage
range.
Wiring
Be sure to wire the E2A and load correctly, otherwise it may be dam-
aged.
Connection with No Load
Be sure to inser t loads when wiring. Ma ke sure to connect a proper
load to the E2A in operation, otherwise it may damage internal ele-
ments.
Do not expose the product to flammable or explo-
sive gases.
Do not disassemble, repair, or modify the product.
Correct Us e
Designing
Power Reset Time
The Proximity Sensor is ready to operate within 100 ms (160ms for
NO+NC -B3 / -C3 types) after power is supplied. If power supplies
are connected to the Proximity Sensor and load respectiv ely, be sure
to supply power to the Proximity Sensor before supplying power to
the load.
Effects of Surrounding Metal
When mounting the E2A within a metal panel, ensure that the clear-
ances given in the following table are maintained.
(Unit: mm)
Note 1. In the case of using the supplied nuts.
If true flash mounting is necessary, apply a free zone of
1.5 mm.
2. In the case of using the supplied nuts.
If true flush mounting is necessary, apply a free zone of
4 mm.
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 sup-
ply has an insulated transf ormer. Do not use a DC power supply with
an auto-transformer.
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.

Wiring
High-tensi on 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 cond uit to pre-
vent against Proximity Sensor damage or malfunctioning.
Cable Extension
Standard cable length is less than 200 m.
The tractive force is 50 N.
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.
Do not tighten the nut with excessive force. A washer must be used
with the nut.
Maintenance and Inspection
Periodically perform the following checks to ensure stable operation
of the Proximity Sensor over a long period of time.
1. Check for mounting position, dislocation, lo oseness, or distortion
of the Proximity Sensor and sensing objects.
2. Check for loose wiring and connections, improper contacts, and
line breakage.
3. Check for attachment or accumulation of metal powder or dust.
4. Check for abnormal temperature conditions and other environ-
mental conditions.
5. Check for proper lighting of indicators (for models with a set indi-
cator.)
Never disassemble or repair the Sensor.
Environment
Water Resistivity
The Proximity Sensors are tested intensiv ely on w ater resistance, but
in order to ensure maximum performance and life expectancy avoid
immersion in water and provide protection from rain or snow.
Operating Environment
Ensure storage and operation of the Proximity Sensor within the
given specifications.
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.
