Precautions
J
TO ENSURE SAFE OPERATION
Do not use the E2ES in places with flammable, explosive
gases.
Do not disassemble, repair, or modify the E2ES.
Make sure that the power supply terminal polarity is correct.
Do not apply AC voltage, or exceed the ratings for DC voltage,
or the E2ES may be damaged or malfunction.
J
MOUNTING
Do not tighten the nut with force exceeding the torque provided in
the following table. A toothed washer must be used with the nut.
Permissible Tightening Torque

180 N S m (1,800 kgf S cm)
J
MUTUAL INTERFERENCE
If more than one E2ES is mounted face to face or in parallel,
make sure that the distances between two units adjacent to each
other are the same as, or larger than, the corresponding values
shown in the following table.

EFFECTS OF SURROUNDING METAL
When mounting the E2ES within a metal panel, ensure that the
corresponding clearances given in either of the following tables
are maintained. These clearances vary depending on whether
the nut provided is used.

METAL CHIPS AND SHAVINGS
The unique circuitry of the E2ES allows it to ignore the
accumulation of metal chips or shavings on the face of the
sensor while continuing normal operation. However, there are
instances where this feature can be compromised, and the face
of the sensor will need to be cleaned.
For Metal Chips

16 mm (0.63 in)

E2ES-X8D1
28 mm (1.10 in)
18 mm (0.71 in)
If a chip of size "d" or greater is on the face of the sensor, clean
the sensor to assure proper operation.
For Metal Shavings
If the metal shavings accumulated on the sensor face are
pressed on (through contact with sensing target or machine, etc.)
the performance of the sensor may be compromised, and the
sensor should be cleaned immediately.
