JEFFECTS OF SURROUNDING METAL
When mounting the E2E2 within a metal panel, ensure that the
clearances given in the table below are maintained. Failure to
maintain these distances may cause deterioration in the perfor-
mance of the sensor.

JINSTALLATION
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 before supplying power to the load.
Power OFF
The Proximity Sensor may output a pulse signal when it is turned
off. Turn off the load 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.
Target Object
Metal Coating
The sensing distances of the Proximity Sensor vary with the
metal coating on target objects.
JWIRING
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 prevent against Proximity Sensor damage or
malfunctioning.
Cable Tractive Force
Do not pull cables with the tractive forces exceeding these specs.
Diameter Tractive force
4mmdia.max. 30 N max.
4 mm dia. min. 50 N max.
JMOUNTING
The Proximity Sensor must not be subjected to excessive shock
with a hammer when it is installed, or the Proximity Sensor may
be damaged or lose its water-resistance.
JENVIRONMENT
Water Resistance
Do not use the Proximity Sensor underwater, outdoors, or in the
rain.
Operating Environment
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 resistant, a cover to pro-
tect 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 concentrated sulfuric acid gases).
