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 short-circuit protection function will be valid if the polarity
of the supply voltage imposed is correct and within the rated voltage
range.
Correct Use
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 respectively, 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.
Note 1. In the case of using the supplied nuts.

If true flash mounting is necessary, apply a free zone of
1.5 mm.
If true flush mounting is necessary, apply a free zone of
4 mm.

Wiring
Be sure to wire the E2A and load correctly, otherwise it may be dam-
aged.
Connection with No Load
Be sure to insert loads when wiring. Make 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.
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 transformer. 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.
