Precautions
Safety Precautions
Power Supply
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.
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 polar-
ity of the supply voltage imposed is correct and within the rated volt-
age range.
Wiring
Be sure to wire the E2EM and load correctly, otherwise it may be
damaged.
Connection with No Load
Be sure to insert loads when wiring. Make sure to connect a proper
load to the E2EM in operation, otherwise it may damage internal ele-
ments.
Do not expose the product to flammable or ex-
plosive gases.
Do not disassemble, repair, or modify the prod-
uct.
Correct Use
Designing
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 Sen-
sor before supplying power to the load.
Effects of Surrounding Metal
When mounting the E2EM within a metal panel, ensure that the
clearances given in the following table are maintained.

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.
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.
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.
