E3S-C

Optical axis position of through-beam model

Unlike the conventional product, the through-beam model has

two lenses, but the one actually used is as shown below.

When fitting the slit, use it after matching the slit hole with the

used lens.

Water Resistance

To ensure water resistance, tighten the operation panel cover

screws to 0.34 Nm to 0.54 Nm torque.

Miscellaneous

Oil resistance/chemical resistance

• Though E3S-C has a high oil resistance, it may not be able

to exhibit its performance depending on the oil type. Use oil

in compliance with the following table.

• Regarding the oil resistance of E3S-C, it has passed tests

on the oils given in the following table. Refer to the table for

examining the oil to be used.

Note: 1 . The E3S-C was immersed in the oils in the above table at 50°C for 240

hours, and passed the test of 100-M

W or more insulation resistance.

2 . For use in the environment where the E3S-C is exposed to the oil other

than those in the above table, use the dynamic viscosity and PH in the

above table. Pre-examine the oils since the sensor may be affected by

additives and like in the oils.
