EFFECTS 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.

INSTALLATION

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.

J

WIRING

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.

J

MOUNTING

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.

J

ENVIRONMENT

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).
